A ferromagnetic material is heated above its curie temperature....

A ferromagnetic material is heated above its curie temperature. Which one of the following is the correct statement?

Options

  1. AFerromagnetic domains are perfectly arranged
  2. BFerromagnetic domains become random
  3. CFerromagnetic domains are not influenced
  4. DFerromagnetic material changes into diamagnetic material

Correct answer

B. Ferromagnetic domains become random

Step-by-step solution

Beyond curie temperature, ferromagnetic material turns into paramagnetic material, as if ferromagnetic domains become random.
