Why does a magnet have a north and south pole?

Cutting a magnetic bar in half will not strip off its poles. It will only produce two magnets, each with a north pole that will be attracted to the south pole of the other magnet, and vice versa.

It is this basic property of attraction that makes magnets useful for so many purposes, from holding a party invitation to the fridge to making medical imaging.
