Question

Why does a freely suspended magnet always rest in north-south direction?

Answer 1

The earth behaves like a magnet with its south pole in the geographical north and the north pole in the geographical south. Due to the attraction between unlike poles, the north pole of the earth’s magnet attracts the south pole of suspended magnet, and the south pole of the earth’s magnet attracts the north pole of the suspended magnet. That’s why a freely suspended magnet always rests in the north-south direction
