Question

In which direction does a suspended bar magnet come to rest? give reason.

Answer 1

1. When a magnet is suspended freely, it always rests in the north-south direction.
2. It happens because the earth itself acts as a huge magnet whose north pole is towards the geographical south and south pole towards the geographical north.
3. We know that two like poles repel and unlike poles attract.
4. The earth's north pole attracts the south pole of the external magnet and its south pole attracts the external magnet's north pole.
5. In this way, the magnet always rests in the north-south direction.
