An iron bar magneti is heated to 1000^@C...

An iron bar magneti is heated to `1000^@C` and then cooled in a magnetic field free space. Will it retain magnetism?

Text Solution

Verified by Experts

No, it will not retain magnetism. Curie temperature for iron is about `750^@C`. At this temperature, it will become paramagnetic and lose its magnetism on heating further. Hence it will not retain magnetism on cooling in a mangetic field free space.
