What are magnets?
A magnet is a very special metal that produces a magnetic field. All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other.
When a magnet goes near a special kind of metal or other magnets, it pulls, or attract the other metal or magnet closer.
Those special metals are Iron, cobalt, and nickel.
Metals that have iron in them attract magnets well. Steel is one.
Metals like brass, copper, zinc, and aluminum are not attracted to magnets.
Magnets can make some other metals into magnets when they are rubbed together.
