Paramagnetic, diamagnetic and ferromagnetic materials
Paramagnetic materials have a small, positive susceptibility to magnetic fields. These materials are slightly attracted by a magnetic field and the material does not retain the magnetic properties when the external field is removed. Diamagnetic materials create an induced magnetic field in a direction opposite to an externally applied magnetic field and are repelled by the applied magnetic field. It has a negative and small value of magnetic susceptibility. Ferromagnetic materials have large magnetic susceptibility and are characterized by non-linear relation between magnetic field (B) and magnetic intensity (H).They show the property of hysteresis.
