Magnetism Question 139
Question: A ferromagnetic material is heated above its curie temperature. Which one is a correct statement
[MP PET 1995]
Options:
A) Ferromagnetic domains are perfectly arranged
B) Ferromagnetic domains becomes random
C) Ferromagnetic domains are not influenced
D) Ferromagnetic material changes itself into diamagnetic material
Show Answer
Answer:
Correct Answer: B
Solution:
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.
