Diamagnetic substances are those substances which are weakly repelled by magnetic field.Some of the properties of these substances are: 1)diamagnetic substances contain even no. Of electrons.Due to which in the absence of magnetic field ,their individual atoms has zero magnetic moment. 2)they do not follow curie law. 3)these substances are temperature independent. 4) permitivity <0 ,permeability<1,u< ur. EXAMPLES:bismuth,copper,lead,silicon.

Diamagnetic substance: Diamagnetic substances are those substances which are repelled by a magnet. From microscopic point of view, these are the substances whose atomic orbitals are completely filled. The cause of magnetization for these substances is the orbital motion of electron in which velocity of the electron is affected by the external magnetic field. Some examples of diamagnetic substances are antimony, bismuth, copper, lead, gold, silver, zinc, quartz, mercury, alcohol, sodium chloride, water, hydrogen, air, argon etc.
