Question

At Curie temperature the ferromagnetic materials get converted into.

• A. non-magnetic material.
• B. para magnetic material.
• C. dia magnetic material.
• D. all of the above.

Answer 1

The correct option is B para magnetic material.

Above curie temperature ferromagnetic material behaves like paramganetic materials. There magnetic susceptibilty starts varying linearly with temperature. Their $I$ becomes too small above curies temperature.

Therefore, nature of ferrromagnetic materials becomes paramagnetic.
