Hi Shaikat Debnath

Broadly speaking, different densities of states for spin up and down lead to the presence of unpaired electrons which, in turn, give rise to magnetism. The spins of unpaired electrons have a magnetic moment and act like tiny magnets. Those magnets interact with an external magnetic field (which is magnetism as mentioned above).

Hope it helps,

It indicates the presence of unpaired electrons in the system and it results in the net magnetic moment of the system.
