1) A magnet attracts magnetic materials towards itself.
2) A freely suspended bar magnet always aligns in the north-south direction.
3) Unlike poles attract each other and like poles repel each other.
4) A magnet with a single pole does not exist. If a magnet is cut into two pieces each piece will behave like an independent magnet, with a north pole and a south pole.
5) When a bar magnet is rubbed over an iron bar, it changes the iron bar into a magnet.
