Electricity and Magnets

Electricity

Electricity is the flow of an electric charge

Magnets

The name magnet came from magnesia, which in a place in Asia found lodestones long ago

Magnets are made of rock that have iron that becomes magnetized

The Electron Cloud

The Electron Cloud has many different parts, there’s the protons, electrons, neutrons, and the nucleus

The Electron Cloud is what makes up an atom

Series Circuit

You know you created a series circuit when each light bulb is connected from one to another and the bulbs light up

If the bulbs don’t light up it means the circuit isn’t complete.

Circuit

Electric current flows when there is a path that it can follow. The path is called a circuit. In a circuit a battery pushes the electric charges from place to place. The push of the battery gives the charges voltage. The word volt is the unit to measure voltage.

Parallel Circuit

In a parallel circuit you can connect bulbs and batteries. The electric current can follow more than one path in a parallel circuit.

Circuit Diagram

A circuit diagram is basically circuit symbols.

Electromagnet

An electromagnet is made up of an iron core, and a metal wire.

One of the world’s largest electromagnet was built in Ontario, Canada. When it was being tested a worker was walking passed it with a knife in his pocket, and the electromagnet pulled the knife out of his pocket, and slammed it against it from 7 feet away!

Electric Current

Electric wires make a path for electricity to pass through them. Electricity can also be called electric current. The steady flow of electric charges moving from one place to another is an electric current.

Electric Charge

Matter is made up of atoms. And atoms have electric charge. There charges can be positive or negative. Rubbing things together makes the charges jump from one object to another. It causes the two objects to have opposite or unlike charges.

Static Electricity

When your shoes rub against a rug your shoes gain electric charges. The electric charges spread across your body, which makes static electricity! So when you touch a doorknob after that you will feel a shock.
