Which of the following statements are correct?

Options

A. Ferrimagnetic substance lose ferrimagnetism on heating and become paramagnetic
B. Ferrimagnetic substances do not lose ferrimagnetism on heating and remain ferrimagnetic
C. Antiferromagnetic substances and their mangetic moments are not cancelled by each other
D. In ferromagnetic substances, all the domains get orieneted in the direction of magnetic field and remain as such even after removing magnetic field.

Answer

A,D

Explanation

Ferrimagnetic substances lose ferrimagnetism on heating and become paramgnetic. In ferromangetic sujbstance, domains are aligned in parallel and antiparallel direction in unequal numbers.
In ferromagnetic substances, all the domains getoriented in the direction of magnetic field and remain as such even after removing magnetic field.
