- D _ d _ = 0 and _ f _ = 0.
Step-by-Step Verified Solution
The magnetic dipole moment of diamagnetic material is zero as each of its pair of electrons have opposite spins, i.e., _ d = 0.
Paramagnetic substances have dipole moment > 0, i.e. _ p � 0, because of excess of electrons in its molecules spinning in the same direction.
Ferro-magnetic substances are very strong magnets and they also have permanent magnetic moment, i.e. _ f � 0.
