Why does an anti-ferromagnetic substance have zero resultant magnetic moment?

Having highest magnetic moment.

(a) Based on the nature of intermolecular forces, classify the following solids: Sodium sulphate, Hydrogen. (b) What happens when CdCl_(2) is doppd with AgCl? ( c) Why do ferrimagnetic substances show better magnetism than antiferromagnetic substances?

Define: (i) ferromagnetic (ii) ferrimagnetic and (iii) anti-ferromagnetic substance. Give one example of each substance.

Compare paramagnetic , diamagnetic and ferromagnetic substances on the basis of magnetic permeability and magnetic susceptibility .

Rank the following magnetic substances in order of their magnetic moments in presence of a magnetic field: Ferrimagnetic, Ferromagnetic, Anti-ferromagnetic

Two identical bar magnets having magnetic moments 2p_(m) and3p_(m) are kept one over the other in such a manner that their opposite poles are in contact . Determine the resultant magnetic moments in each case .

The value of magnetic moment is zero in the case of anti-ferromagnetic substances because the domains-
