Explication
Paramagnetism occurs when an atom or material has unpaired electrons, which act like tiny magnets due to their spin. The magnetic moment of an electron is a result of its spin and orbital motion. Paramagnetism in transition metals is caused by the presence of unpaired electrons in their atomic and ionic species.
