GEOLOGY

Detailed explanation-1: -Every magnet has both a north and a south pole. There are no magnets with only one pole (see magnetic monopoles). With an axially magnetized disc magnet, for example, you could write a big N and an S on either round face with a marker.

Detailed explanation-2: -Solution: A freely suspended magnet always rests in the north-south direction because the magnetic south pole of the earth lies in the geographic north direction and the magnetic north pole of the earth lies in the geographical south direction.

Detailed explanation-3: -A magnet has two ends called poles; one end is the north pole and the other is the south pole. A north pole will attract a south pole; the magnets pull on each other. But the two north poles will push each other away. We say the magnets repel each other.
