Paramagnetism

Vedclass · Answer

(C) The correct answer is $C$. Paramagnetism is a property exhibited by substances whose individual atoms possess a permanent,non-zero magnetic moment. This occurs because these atoms have an excess of electrons spinning in the same direction,resulting in a net magnetic moment for each atom. In the absence of an external magnetic field,these individual magnetic moments are randomly oriented due to thermal agitation,resulting in zero net magnetization for the bulk material.

Substances in which the magnetic moment of a single atom is not zero are known as:
