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
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.
