ELECTROMAGNETIC FORCE (Level 4)

IDEA PAGES

I. UNIT THEMEElectromagnetic force is one of four main forces in the universe and has

many useful applications in everyday life throughout the world. Electricity and magnetism are two forms of the single phenomena,

electromagnetic force.Many scientists have contributed to this field, and their work is built upon

the foundation of previous research and discoveries.

IV. CONCEPTSAtoms have negatively charged electrons that spin around a nucleus of

positively charged protons and neutrons.Charges fill space with an electric field.Static electricity is associated with the gain or loss of electrons.Electromagnetic forces can attract or repel.Opposite electrical charges attract each other, and like electrical charges

repel each other.Electric current is the flow of electrons.A complete, continuous path of current is called an electric circuit.Conductors are materials that allow energy to flow and carry out current.

Simple, series, and parallel circuits can be built by using materials such as wires, batteries, and bulbs.

Magnetic materials are sources of magnetic fields.The Earth has a magnetic field caused by electrical currents.Magnets have two poles; like poles repel and unlike poles attract.Electric current, like magnets, produce magnetic fields.Electromagnets are used in many simple devices, tools, and appliances.Electromotive forces are produced in a wire whenever a magnetic field cuts

across the wire.Safety when using electromagnetic forces

The Important Book about ElectricityBy Marita d’Arnaud

An important thing to remember about electricity is that it has many useful applications in everyday life.

Electricity is one form of electromagnetic force. A force is a push or a pull.Electricity is related to magnetism, the other form of electromagnetic force.Electrical energy, which comes from charged particles, allows us do many things

like play a PlayStation II game, toast bread in a toaster, and drive an electric car.

But an important thing to remember about electricity is that it has many useful applications in everyday life.

An important thing to remember about electricity is that it has many useful applications in everyday life.

Negatively charged electrons(-) in atoms spin around a nucleus of positively charged protons(+) and neutrons(0), which have no charge.

When atoms lose or gain electrons, the atoms become charged.Charges fill space with an electric field.Opposite charges attract each other, and like charges repel each other.

When negative charges move from one object to another, charge builds up on both objects.

One object will have a positive charge. The other will have a negative charge.This buildup of charges is called static electricity.Built-up charges can leak out harmlessly or “jump” causing an electrical

discharge, like lightning or an electrical shock.But an important thing to remember about electricity is that it has many useful applications in everyday life.

A stream of moving electrons produces an electric current.An electric circuit is a complete, continuous path of current.Conductors, like copper and aluminum, are materials that allow current to flow

easily. Insulators, like rubber and plastic, do not allow current to flow.But an important thing to remember about electricity is that it has many useful applications in everyday life.Electromagnetism Level 4 26By Mountain View School District - Project G.L.A.D. (Rev. 09/06 JB)

An important thing to remember about electricity is that it has many useful applications in everyday life.

Simple, series, and parallel circuits can be built using materials such as wires, batteries, switches, and bulbs.

As current flows through a bulb, electrical energy is converted to heat and light energy.

As electric current flows, a magnetic field is produced. A moving magnetic field creates an electric current.

Electricity allows us to turn on lights, play videogames, use a microwave, and watch television.

An important thing to remember about magnetism is that it has many useful applications in everyday life.

Just as an electric current produces a magnetic field, a changing magnetic field produces an electric current.

A coiled wire with an electric current has a stronger magnetic field than a straight wire with current.

Inserting an iron bar into the coil creates an electromagnet, with an even stronger field.

Electromagnets are used in electric generators, motors, and simple devices such asdoorbells, VCRs, telephones, and loudspeakers.

THE LEGEND OF MAGNES

A legend is a story about an event that happened a long time ago. Usually, a legend has some truth to it, but untruths have often been added through the years. There is a Greek legend about how magnets were first discovered.

Thousands of years ago, an old man named Magnes was herding his sheep. As he walked his sheep through the fields, he climbed on a large, black rock to get a better view.

Something strange happened. The nails in his shoes and the metal at the tip of his shepherd’s staff stuck to the rock! He lifted his feet out of his shoes and left his staff to go tell the townspeople of Magnesia what happened.

They came to look at the mysterious rock. The townspeople were amazed. Magnes then removed his shoes and staff and went on his way. The townspeople named the black rock “magnetite” after the old man and the town nearby.

Over the years, legends were made up about the power of magnetite.Some legends told of magnetite having magical powers. Others told of magnetite healing the sick and driving evil spirits away. Sailors told legends of ships made of iron being attracted to magnetite rocks only to be crushed and shipwrecked.

Famous Scientists TimelineL. Ruvalcaba MVSD GLAD 2005

470 BC Democritus Greek philosopher - theorizes about the atom.Theorized that all matter was made up of invisible particles called atoms. His idea was rejected at the time because it could not be proved. He was even suspected of being insane.

625-547 BC Thales Ancient Greek scientist, Thales, observed that an electric charge could be generated by rubbing amber with a piece of wool or fur, the greek word for electron

1600 William Gilbert English Scientist - first to study about thelines of force around magnets. He theorizedthat Earth was a large magnet and exerteda magnetic influence (gravity) throughoutthe solar system. He was the first scientistto use the word electric to describe one object’s power to attract others. He made the first electroscope, an instrument thatdetects the presence of an electric charge.

1687 Sir Isaac Newton British Scientist - Explained how all objectsin the universe, even the planets, move. His laws of motion used math and he made predictions, for the first time. Scientists still consider Newton the most famous physicist ever.

1752 Benjamin Franklin American statesman and inventor. He provedthat lightning was static electricity, invented the Franklin stove, bifocal glasses, and the lightning rod.

1769 James Watt Scottish engineer – made important improvementsto the steam engine, thereby helping to stimulate the Industrial Revolution. He was the first personwho coined the term, horsepower. The basicmeasure of electric power is the watt, which wasnamed in his honor.

1800 Alessandro Volta Italian physicist. Discovered that 2 metals incontact could create an electric current. Created the first electric battery and condenser. Invented the electrophorous to show static electricity, a device with two metal plates that can make an electrical charge. Volt (modern unit of electric potential, which is the strength or “electric push” of the flowing charge) named after him

1803 John Dalton English scientist provided proof that atomsexisted. His atomic theory states that all matter is made up of small, indivisible particles called atoms. Atoms of different particles have different properties, but all atoms of the same element are identical. Atoms cannot be created or destroyed.

1819 Hans Christian Oersted Danish Scientist – discovered electromagnetismHe was conducting an experiment with an electricalcircuit and noticed that when he turned the circuiton and off the needle of his nearby compass wouldjump. He concluded that electricity produces magnetism. His discovery became the basis of the electric motor and the electromagnet.

1826 Georg Ohm Made an important discovery about resistance. Hestudied the relationship between the amount ofcurrent that flowed through a wire(amperage) andthe amount of EMF that drove the current (voltage).

1830’s Andre Ampere French scientist - Discovered that if he passed anelectric current through a coil of wire, the wireacted like a magnet. The basic unit of electric current flow is named “ampere.”

Page 33: PROJECT GLAD · Web view1893 Nikola Tesla Croatian Scientist – invented AC power (alternating currents) An alternating current flows alternately in either direction, and its voltage

1831 Michael Faraday British Scientist – Conducted an experiment devisedto bring about the conversion of magnetism to electricity. He imagined that there were “lines of force” stretching out in space from a magnet. He discovered electromagnetic induction, a varying or moving magnetic field produces an electromotive force emf in a nearby conductor, and thus an electric current if the conductor is part of a circuit. Constructed the first electric generator.

1847 Alexander Graham Bell Born in Scotland, emigrated to America in 1871. American scientist and inventor. He found that different voice tones could vary the electrical signals flowing in a wire, by the process of electromagnetic induction. Invented an early version of the telephone.

1865 James Clerk Maxwell Scottish physicist. Developed the math todescribe electric and magnetic fields and how theyaffect each other. He showed that magnetic fieldsand electric fields always exist together, so thefield is really an electromagnetic field. Maxwellalso produced a theory about what light is and howit moves.

1873 Demitri Mendeleyev Siberian scientist devised his periodic table ofelements. He used the atomic weights of elementsand grouped the elements according to similarproperties, such as how they react with oxygen.This gave him seven different groups of elements.He made the claim that “properties of the elementswere periodic functions of their atomic weights.”Mendeleyev called this the periodic table of elements because the chemical properties repeated themselves every seven elements.

currents) An alternating current flows alternately ineither direction, and its voltage can be easily controlled. Tesla showed that AC power could be transmitted efficiently at high voltages over great distances. When it reached the points it was to be transferred into homes, devices called transformers could decrease the voltage to safe levels. Tesla invented all the different components of the entire AC system – generator, transformer, transmission lines, motor and lights.

1898 Marie Curie Polish scientist – discovered the element radium. Famous for her discoveries in field of radioactivity. Discovered that a small amount of radium would destroy human tissue.

1905 Albert Einstein German scientist – Most famous for his theory ofrelativity. One of the most famous discoveries in allscientific history was the amount of energy storedin matter. If the amount of energy that is stored injust one pound of coal could be converted intoenergy it would produce the amount of electricity the entire world uses in one day.

NARRATIVE INPUT

Katrina Faber, her sister Carla, and their parents are spending Saturday afternoon at the Franklin Institute Science Museum in Philadelphia. “Hey kids, come look at this! It’s an exhibit on Ben Franklin’s inventions. He was from Philly, you know, just like us,” said Mrs. Faber.

“No, he was born in Boston!” Carla quickly added. Mrs. Faber stated that he lived in Philadelphia, Ben’s favorite city, most of his life.

“Wow! This is pretty incredible! Look at all the things he invented. Wood stoves…bifocals…” Mr. Faber exclaimed. Katrina wanted to know what bifocals were. Carla explained that they are special glasses with two lenses. The top is for viewing long distances while the bottom half is for reading. Then Mr. Faber continued to explain how old Ben got tired of switching his regular glasses to his reading glasses that he combined the two and invented bifocals.1

Katrina sat down on a bench while her family continued looking at exhibits. As Mrs. Faber started talking about Franklin discovering electricity, Katrina noticed an oddly dressed elderly man. He was wearing a shiny suit with ruffles at the wrists, and his pants went down to his knees. His shoes had silver buckles on them. Still, Katrina was sure she’d seen him somewhere before. “It never happened,” the stranger spoke.

“What?” asked Katrina.“I never discovered electricity.” Katrina stared at the stranger and

was dumbfounded. “What, you don’t recognize old Ben? Ben Franklin?” Ben said.

“You can’t be Ben Franklin, he was born a million years ago!” Katrina remarked.

“Would you offer him a seat if he were here?” asked Ben. Katrina nodded.2

Ben sat down next to Katrina and kicked off his shoes and asked her what they were talking about. Katrina couldn’t believe that he had already forgotten what they were discussing. “Electricity, Mr. Franklin,” she replied.

3

Ben chuckled and then began to explain how many people thought he discovered electricity however it was the Greeks who discovered it about 3,000 years ago in 600 B.C.E. They weren’t sure how to use it. All they knew was that rubbing amber with a piece of wool would create static electricity. He told her another example of static electricity is when a person takes off their hat in the winter and their hair stands straight up. “That’s electricity?” Katrina asked.

“Sure. It’s just like your TV,” Ben answered. Then Katrina gave Ben a puzzled look and he replied, “I keep up. Here, close your eyes for a second and I’ll show you exactly how I discovered that lightning was made out of electricity.”

4

When Katrina opened her eyes, she found herself in a living room of a house. There was a paper on the table that resembled a newspaper with date 1752. Ben was there, with his shoes on, sitting in a chair talking to his son named William. He asked him what he was doing for the day and if he wanted to help perform an experiment. She could then hear Ben saying, “It’s going to be a rainy evening. It’s perfect weather for our electrical experiment. Let’s get started.” Katrina watched as they made a kite out of two crossed strips of cedar wood and an old handkerchief. Then they attached a piece of wire to one of the strips. She wondered if they needed her help or if they could even see her.

5

The two went outside and Katrina followed. She heard Ben tell William how electricity was discovered hundreds of years ago. Yet, nobody

Page 40: PROJECT GLAD · Web view1893 Nikola Tesla Croatian Scientist – invented AC power (alternating currents) An alternating current flows alternately in either direction, and its voltage

really knew what it was, or how to use it, or if it could be used. “Is it magic?” she heard William ask.

“It’s not magic. I suspect it comes from nature. My guess is that lightning is made of electricity. That’s what I hope we can prove tonight. Metal attracts electricity. I think it attracts lightning, too,” Ben said. He then took the kite and tied a large metal key to it. Ben held onto the string as William ran with the kite. A strong wind took the kite high into the air.

6

“Hey wait! That’s really dangerous! I heard about someone who got hit by lightning on a golf course and got badly hurt! Hey! Can your hear me?” Katrina yelled. Ben and his son didn’t hear Katrina’s warning.

“Direct me towards the darkest cloud, William!” Ben instructed. Lightning was flashing all around them, and finally it struck the wire on the kite. Ben reached for the key and yelled, “Yeow!” A spark flew off the key and zapped him.

“Did electricity travel down the string? Was that spark electricity?” William asked.

“It most certainly was! We’ve done it, William! We’ve proven that lightning is made of electricity!” exclaimed Ben.

7

“How does this help us?” asked William. Ben put his arm around William and began telling him how he thought he could prevent houses from burning down to the ground that get struck by lightning. He explained that lightning is attracted to metal, and that lightning usually strikes the tallest thing around. Katrina then heard Ben tell his son that if he put a tall metal pole on every house, the lightning would hit the pole instead of the house. “Katrina, it’s time to go!” William said.

“What? You can see me?” Katrina said.“I said it’s time to go!” William said again.

Katrina blinked and found that she was sitting on the bench at the Franklin Institute. Katrina’s dad was shaking her on the shoulder. “Hey Katrina, it’s time to go! I said, it’s time to go! Have you been sleeping on this bench all afternoon?” Mr. Faber asked.

Carla laughed, “I’ll bet you’ve really learned a lot.” “I learned plenty today,” Katrina responded. She then went into detail

about the story of Ben and his son discovering that lightning was made of electricity and how he put that discovery into inventing the lightning rod. “Where did you learn that?” asked Mrs. Faber.

“Ben Franklin told me. I mean, I must have read it somewhere,” Katrina stammered. Mr. Faber had then said that it was time to hit the road.

9

“I need to get a drink of water first. I’ll hurry,” Katrina said. Just as she was getting a drink she noticed someone carefully studying the electricity exhibit. It was Ben. “Mr. Franklin, your still here. I told my parents about the lightning rod. That was great,” Katrina said. With a smile on Ben’s face, he told Katrina of some other amazing accomplishments during his time. He told her how he formed the first fire department, established the first free library, invented the wood stove, signed the Declaration of Independence, and the Constitution. He even went to France to raise money for the American Revolution. “Wow, I can’t even finish all of my homework sometimes!” Katrina said.

“People can accomplish a lot if they believe in themselves and work hard. Nothing is so complicated that we can’t understand it. All you have to do is slow down and think it through carefully. Pretty soon it’ll make sense to you. When I was young there were a million things we didn’t understand about science and medicine. But, I read everything I could, spent lots of time thinking about things. Try it. You’ll be surprised what you might discover.” Ben said. Just then Ben pulled a penny from behind Katrina’s ear and handed it to her. “Here’s a penny for your thoughts,” he said.

“How did you do that?” Katrina was shocked.“It’s magic,” Ben replied.“Thanks, Mr. Franklin. Thanks for everything,” Katrina said

11

That night Mrs. Faber went to tuck Katrina into bed. They discussed the events of the day and their favorite exhibits. As Mrs. Faber went to turn the light off she noticed something shiny on Katrina’s desk and picked it up. “This penny is from 1789. Where did you get this?” Mrs. Faber asked.

Katrina smiled, “An ‘old’ friend gave it to me.”

I’M AN ELECTRICAL ENGINEER

I’m an electrical engineer, and here to sayI study how charges move everyday.

Sometimes I plan a circuit or read a physics book,Sometimes I analyze how electromagnets look.

Conductors, voltage, and resistance, tooThe Electrical Current Bugaloo!

I study electricity and where it flows,When switches are flipped, well, there it goes.

It travels through conductors often wrapped in insulators,Currents can convert to light, and cool refrigerators.

Expert GroupsStatic Electricity

DefinitionWhen electrical charges have built up on the surface of an

object, static electricity is created. For example, when a balloon is rubbed against your hair, electric charges build up on the surfaces of the balloon and your hair.

Components (parts)All matter is made up of tiny particles. Some of these particles

carry units of electricity called electric charges. These charges can be positive (+) or negative (-). Most matter is neutral, which means that the number of positive charges and negative charges are equal. Only negative (-) charges can move from one material to another. When charges transfer from one neutral object to another, the first object is left with a positive (+) charge. The second one has gained negative (-) charges. Therefore, it has a negative charge.

PropertiesLike charges repel, or push away, one another. Unlike charges

attract, or pull toward, each other. Eventually, electrically charged objects will lose their “charge”. These charges may simply leak away slowly into the air. Charges may also “jump” between materials. When electric charges move off of a charged object, an electric discharge takes place. This is called static electricity.

Contributing ScientistsIn 1752, Benjamin Franklin conducted a famous experiment in

which he attached a metal key to a kite. Franklin flew this kite during a thunder storm and proved that lightning is indeed static electricity. Electromagnetism Level 4 60By Mountain View School District - Project G.L.A.D. (Rev. 09/06 JB)

Page 61: PROJECT GLAD · Web view1893 Nikola Tesla Croatian Scientist – invented AC power (alternating currents) An alternating current flows alternately in either direction, and its voltage

He showed that lightning occurs when there is a positive (+) build up at the top of the storm clouds. The negative charges build up at the bottom of the clouds. These negative charges repel the negative charges on the ground, making it and any surrounding objects positively charged. Because opposite charges attract, the negative charges from the cloud “jump” toward the closest positively charged object creating a GIANT electrical discharge. This discovery led to Franklin’s invention of the lightning rod. The rod is attached to the top of buildings and is connected to the ground by heavy wires. It is through these wires that the electric charge can safely move toward the ground.

ApplicationsToday, static electricity is useful in our everyday life. For

example, as a form of pollution control, an electric static precipitator is used to charge dirt particles in the air and then collect them. People use products such as hair diffusers to dry curly hair, air purifiers (ionizers), photocopiers and paint guns, all of which use static electricity.

Electric Currents

DefinitionElectricity is a form of energy produced by the movement of

electrons. When there is a steady flow of electrons (negative charges) through a given path, an electric current is created. This path that the current travels through is called an electric circuit.

PropertiesElectric currents travel easily through various forms of matter

such as water and metal. These materials are called conductors. Metals such as gold, silver and copper are good conductors of electricity. Materials that are poor conductors are known as insulators. Wood, rubber, plastic, glass and cork are a few examples. Copper wires that are used to carry electric currents are coated with rubber. This rubber serves as an insulator. The insulator helps maintain the strength of the electric current within the wire and it also protects us from receiving an electric shock.

Components (parts) / Contributing ScientistsElectricity flows through Direct Current (DC) and Alternating

Current (AC). In a direct current, electricity flows continuously in one direction. Electric cells and batteries for flashlights are examples of DC. Thomas Edison’s first power plant could only transmit Direct Current (DC) power over one square mile. It was transmitted through thick dangerous cables. Edison’s direct current power was not safe for homes, schools or buildings because it produced too much voltage (amount of electricity) at once.

Page 63: PROJECT GLAD · Web view1893 Nikola Tesla Croatian Scientist – invented AC power (alternating currents) An alternating current flows alternately in either direction, and its voltage

Nikola Tesla, a Croatian physicist who came to America, found a solution to Edison’s problem. Tesla discovered that an Alternating Current (AC) could transmit electricity more efficiently at high voltages over great distances. In an Alternating Current (AC), the electricity flows one way around a circuit and then quickly switches back around in the opposite direction at a rate of fifty times per second. Tesla taught Edison about AC and explained that the voltage could easily be decreased to safe levels through transformers for daily use. The electricity in our homes and schools is AC.

Applications Computers, video games, TVs and radios all rely on components

that control, change and manipulate electric currents. In fact, we depend on electric currents to supply energy to just about everything we use in our daily lives.

Electromagnets

DefinitionAn electromagnet is a powerful temporary magnet that is made

when an electric current passes through a wire coiled around a piece of ferromagnetic material, often an iron core. In an electromagnet, electricity is used to create magnetism.

Components (parts)When an electric current moves through a wire, the wire

becomes surrounded a magnetic field. The magnetic field of the current is comprised of concentric circles, centered on the wire and lying in the plane perpendicular to the current. By tightly winding the wire many times around the magnetic field becomes stronger and more concentrated. If this is done around a cylinder, a solenoid coil with a magnetic field similar to a bar magnet is created. When an iron core is placed inside the wire coil, the magnetic field is strengthened, and the result is an electromagnet.

Interesting Facts/ Contributing ScientistsOne can find the direction by using the right hand rule. By

pointing the thumb on your right hand along the direction of the current, the fingers curl in the direction of the magnetic field. The scientist, Ampere discovered that the magnetic fields of two parallel currents cause an attraction between each other.

PropertiesAn electromagnet is similar to a natural magnet is some ways.

First, they both attract materials that contain iron and certain other Electromagnetism Level 4 64By Mountain View School District - Project G.L.A.D. (Rev. 09/06 JB)

Page 65: PROJECT GLAD · Web view1893 Nikola Tesla Croatian Scientist – invented AC power (alternating currents) An alternating current flows alternately in either direction, and its voltage

metals. Next, they both have north and south poles. Electromagnets also have magnetic fields.

Electromagnets and permanent magnets differ in several ways. First, the strength of an electromagnet can be controlled by changing the amount of current flowing through the wire coil. Next, an electromagnet can be turned on and off. Finally, the connections of an electromagnet to a dry cell (battery) can be switched to make the current reverse directions. A compass will show that the poles of the magnet have been reversed. This reversing of poles explains the operation of electric motors.

Contributing ScientistsUntil 1819, everyone believed that magnetism and electricity

were completely separate. In 1819, Danish physicist Hans Oersted discovered that an electric current passing through a wire caused a nearby compass needle to deflect, or move.

Applications

Electromagnets have many useful applications. Enormous, strong electromagnets are used in recycling plants to separate cans made of steel from those made of aluminum. Our homes are filled with items that use them. Doorbells, telephones, VCRs and cassette players have electro-magnets. When a doorbell is pressed, a circuit closes and the electromagnet pulls on a hammer which strikes a bell. Electric motors rely on electromagnets as well. These motors run clocks, fans, refrigerators, vacuum cleaners and hair dryers.

Electric Circuits

Definition and PropertiesFor electricity to be useful, it must flow through a continuous,

open path. This path along which negative electric charges can flow is called a circuit.

Electromagnetism Level 4 65By Mountain View School District - Project G.L.A.D. (Rev. 09/06 JB)

Page 66: PROJECT GLAD · Web view1893 Nikola Tesla Croatian Scientist – invented AC power (alternating currents) An alternating current flows alternately in either direction, and its voltage

The flow of electrons in a circuit is similar to the water flow in a pipe. The circuit gives the electrons a path in which to flow. The amount of electricity in a circuit depends upon current, voltage and resistance. Current is the rate of the flow of electrons. Voltage is the force that causes it to flow. Finally, resistance is the property that slows or stops the flow of electrons.

Components (parts)There are three types of electric circuits. The simple circuit is

the easiest to build. It begins with a source of electric charges such as a battery (dry cell). A light bulb or other device is then connected to the cell with one copper wire while another copper wire connects the bulb or other device back to the cell.

Another type of circuit is a series circuit. In the series circuit, the same materials are used along with additional light bulbs and a power switch all strung in a row, much like holiday lights.

The parallel circuit is the third type of electric circuit. The same materials are used, but they are connected differently. In a parallel circuit, each bulb or device is directly connected to the battery thus providing each bulb with its own path for electricity to flow to it. Parallel circuits are used in our schools and homes. A switch controls the flow of electricity through the circuit. When the switch is open, the current cannot flow. If the switch is closed, the current can flow.

Contributing ScientistsThomas Edison is primarily responsible for the distribution of

electricity to factories, offices and homes. In 1879, while living in New Jersey, Edison worked on perfecting the electric light. He spent two years searching for the proper filament to provide adequate resistance. After over 7,000 attempts, he succeeded at inventing the electric light bulb. In 1882, Edison and his colleagues had cables installed to neighboring cities in order to distribute electricity to them.

ApplicationsElectric circuits have enabled us to carry out many of our

everyday tasks. Our cities, homes, businesses and schools are all supplied electricity through circuits. It is because of these circuits that we are able to light up dark places, watch TV, play video games and store food in our refrigerators. We have truly become a world dependant on the inventions and discoveries of physicists!
