Properties of paramagnetic Materials :
(1) A paramagnetic substance is feebly attracted by a strong magnet.
(2) When a paramagnetic substance is placed in a magnetic field, the magnetic lines of force prefer to pass through the substance rather than through air. Therefore, the resultant field B inside the substance is more than the external field B0.
(3) When a rod of paramagnetic substance is suspended freely in a uniform magnetic field, the rod comes to rest with its longest axis along the direction of external magnetic field.
(4) When placed in a non-uniform magnetic field, a paramagnetic substance moves from weaker to stronger parts of the field.
(5) The relative permeability (μr) of paramagnetic substance has small positive value.
(6) The magnetic susceptibility of paramagnetic substance varies inversely as the absolute temperature.
