What Are Magnets?
I want to learn how magnets push or pull objects.
Magnets A magnet is an object that attracts iron or steel objects. When objects attract, they pull toward each other. If an object and a magnet attract each other, the object is magnetic.
Most magnetic objects have a metal in them called iron.
QUESTION How can you find out if an object is magnetic?
QUESTION How are magnetic and nonmagnetic objects different?
Do you remember what a force is?
Did you know that magnets act on each other!
All magnets have forces that act on other magnets. The force between two magnets can either be a push or a pull. The poles are the places on a magnet where the forces are strongest. All magnets have 2 poles. A magnet does not have to touch an object to push or pull it.
On some magnets, the poles are labeled N for north pole and S for south pole. 2 unalike poles will attract each other. 2 like poles will repel. When a magnet repels, it pushes an object away from itself.
