which of the following statements are correct ?

Options

A. Ferrimagnetic substance lose ferrimagnetism on heating and become paramagetic
B. Ferrimagnetic substance do not lose ferrimagnetism on heating and Reamain ferrmagnetic
C. Antiferromgnetic substance have domain structures simolar to ferromagnetic substance and their magngnetic moment are not cancelled by eash other
D. in ferromagnetic substance , all the domains get oriented in the directon of magnetic field and ramain as such even after removing magnetic field

Answer

A,D

Explanation

ferrmagnetic lose ferrimagnetism on heating and become paramagnetic in ferrmagnetic substance domains are alligned in parallel and antiparallel direction in unequal numbers
in ferromanetic substance ,all the domains get oriented in the direction of magnetic field and remain as such even after removing magnetic field
Hence (a) and (d) are correct choices.
