Question

Why does a freely suspended magnet always rest in North-South direction??​

Answer 1

Answer:

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.

Answer 2

There is a large South magnetic polarity in the so called North of the Earth. So when a magnet is freely suspended it's north pole gets attracted by the magnetic south polarity of the Earth (in the north direction) and it points to the North directon.

A magnetic north pole is called so because it always points to the north ("North pointing pole").

Hope this answer helps you.
