Substances in which the magnetic moment of a single atom is not zero is known as
Diamagnetic
ferromagnetism
Paramagnetism
ferrimagnetism
As we learned
Magnetic moment (m) -
Very low (In paramagnetic substance)
-
The properly of paramagnetism is found in these substances whose atoms have an excess of electrons spinning i the same direction. Hence atom of paramagnetic substance have a net non-zero magnetic moment of their own.
