Push two bar magnets together on a desk, end to end. They snap together. Flip one around, and now they shove each other apart.
Both tries used the same two magnets. The last lesson named the poles. This lesson gives the rule the poles follow.
Face a north pole toward another north pole. The magnets push apart. Face a south pole toward another south pole. The magnets push apart again. But face a north pole toward a south pole. The magnets pull together.
Two poles of the same kind are called like poles. Two poles of different kinds are called unlike poles.
