The two ends of a magnet are called the east and west poles.

The S pole of a suspended magnet points approximately towards the west.

There are forces between magnets and magnetic materials.

Two north poles of different magnets will attract each other.

Two south poles of different magnets will repel each other.

A north pole and a south pole of different magnets will repel each other.

Magnets attract magnetic materials such as iron, nickel, and cobalt.
