Question

Answer 1

Explanation:

1. Bar magnet is a permanent magnet.
2. Soft iron is the temporary magnet that shows magnetism when current flow through it.
3. First we will suspend these two bars on two different stands with the string freely.
4. Then it is seen that the magnet will come to rest only in the north-south direction.
5. And soft iron will rest in any direction.
