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 domain increases.
In the light of the above statements, choose the most appropriate answer from the options given below:

Accepted Answer

Statement I is true but Statement II is false. Statement I is correct because ferromagnetic materials lose their magnetic properties and become paramagnetic at high temperatures due to thermal agitation disrupting the alignment of magnetic domains. Statement II is false because at high temperatures, the domain wall area does not increase; instead, the thermal energy causes the domains to become less ordered, leading to a decrease in overall magnetization.
