A ferromagnetic material is heated above its curie temperature. Which one is a correct statement?

A

Ferromagnetic domains are perfectly arranged

B

Ferromagnetic domains become random

C

Ferromagnetic domains are not influenced

D

Ferromagnetic material changes itself into dianagnetic material

Text Solution

Verified by Experts

The correct Answer is:
B
On heating, different domains have net magnetisation in them which are randomly distributed. Thus the net magnetisation of the substance due to various domains decreases to minimum.
