11 Do you remember what a force is?

12 Did you know that magnets act on each other!

14 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.

15 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.
