The ends of magnets are called poles. Most of the magnetism is concentrated in the poles.

If you hang a bar magnet from a thread it will come to rest in a direction facing North-South,

 

 

Magnets behave differently depending on which poles you bring together.

 

Bring a North-seeking pole near to a South-seeking pole. The magnets are attracted.

Bring a South-seeking pole near to a South-seeking pole. The magnets repel each other.

 

The Law of the magnet is:	Like poles repel.
	Unlike poles attract.
