magnet•any material that attracts iron
& materials that contain iron•one part always points north

magnetism•attraction of magnet for another object

magnetic pole•1 of 2 ends of magnet•strongest magnetic effect•Like poles repel•Unlike poles attract
Remember, opposites attract!Remember, opposites attract!

magnetic force
•attraction or repulsion between magnetic poles

magnetic field•area of magnetic force around magnet

magnetic field lines• invisible lines
that map out magnetic field around magnet
•spread out from 1 pole curve around magnet return to other pole

The magnetic field of a single bar magnet is altered when another bar magnet is brought near it.

Magnets…• Magnetic field lines• Some planets are magnetic• Opposite poles attract-similar ones do not • North and south pole• Magnets attract• 2 poles both have different forces• World is one big magnet• When you break a magnet, it still works• Magnets make Japanese train move• Magnets have a magnetic field around them
