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 :
Correct Option: 1
Solution:
As temperature increases, domains disintegrate so ferromagnetism decreases and above curie temperature it become paramagnet.
