Question

a magnet rest when faced to north and south direction

Answer 1

Explanation:

A freely suspended bar magnet always comes to rest in the North-South direction. The geographical North facing end of the magnet is its north pole and the geographical south facing end is its South pole. Hence, the unknown poles of a bar magnet can be marked by suspending it freely by a string.

Answer 2

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. As unlike poles attract and like poles repel, a magnet aligns itself in N-S direction.
