  • The ends of the bar magnet are known as the poles of the magnet. The red end is the north pole (north-seeking pole) and the blue end is the south pole (south-seeking pole).

3. Forces between magnets

When magnets are near one another, forces are generated between them. The following experiment will make it possible to find out what these forces are.
