MCQ

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

A
Ferromagnetic domains are perfectly arranged
✓
Ferromagnetic domains becomes random
C
Ferromagnetic domains are not influenced
D
Ferromagnetic material changes itself into diamagnetic material

✓

Answer

Correct option: B.

Ferromagnetic domains becomes random

b
(b)On heating, different domains have net magnetisation in them which are randomly distributes. Thus the net magnetisastion of the substance due to various domains decreases to minimum.
