Question

Difference between ferrimagnetism and ferromagnetism

Answer 1

ferromagnetic substance is that in which all the magnetic domains are aligned in one direction but in ferromagnetic substances some are aligned in one direction and some are in other direction but their number is not equal.
ferromagnetic substances are much stronger than ferromagnets

Answer 2

HEY MATE HERE IS YOUR ANSWER:-

Ferromagnetism :-
these are those substances which exhibit usually large paramagnetism and show permanent magnetism even in the absence of magnetic field.

Ferrimagnetism:-
When magnetic moments or domains are aligned in parallel and antiparallel directions in unequal numbers resulting in small net magnetic moment than the magnetism is called ferrimagnetism and the substances possessing such behaviour called paramagnetic substance.
eg. Fe3O4, MgFe2O4
