Statement I The ferromagnetic property depends on temperature. At high temperature, ferromagnetic 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 below.

View answer and explanation

Correct option: A

Statement I is true but Statement II is false

Option A (Statement I is true but Statement II is false) is correct because ferromagnetic properties are temperature-dependent, but domain wall area does not increase at high temperatures.
