Statement I : The ferromagnetic property depends on temperature. At high temperature, ferromagnet becomes paramagnet.
Question:

Statement I : The ferromagnetic property depends on temperature. At high temperature, ferromagnet becomes paramagnet.

Statement II : At high temperature, the domain wall area of a ferromagnetic substance increases.

In the light of the above statements, choose the most appropriate answer from the options given bclow :

  1. Statement I is true but Statement II is false

  2. Both Statement I and Statement II are true

  3. Both Statement I and Statement II are false

  4. Statement I is false but Statement II is true
