Question

no 24 define both example ​

Answer 1

Answer:

ferromagnetic:- A few substance like iron, cobalt, nickel and gadolinium are attracted very strongly by magnetic field. such substances are called ferromagnetic substances.

Anti-ferromagnetic:- substances like Mno have domain structure similar to ferromagnetic substances but in opposite direction and cancel out other's magnetic moment.

Answer 2

Ferromagnetism is the basic mechanism by which certain materials (such as iron) form permanent magnets, or are attracted to magnets. ... Only a few substances are ferromagnetic. The common ones are iron, cobalt, nickel and most of their alloys, and some compounds of rare earth metals.

Antiferromagnetic substances have domain structure similar to ferromagnetic substance. The domains of antiferromagnetic substance are oppositely oriented and cancel out each other's magnetic moment . Example MnO is a Antiferromagnetic substance.
