Properties :
(1) Diamagnetic substance is feebly repelled by a strong magnet.
(2) When a diamagnetic substance is placed in magnetic field, the magnetic lines of force prefer to pass through the surrounding air rather than through the substance. This is because the induced magnetic field in the diamagnetic substance opposes the external field.
(3) When a rod of diamagnetic substance , is suspended in a uniform magnetic field the rod comes to rest with its longest axis at right angles to the direction of the field.
(4) When placed in a non-uniform magnetic field, a diamagnetic substance moves from stronger to weaker parts of the field.
(5) The relative permeability (μr) of a diamagnetic substance is always less than 1.
(6) The magnetic susceptibility (χ) of a diamagnetic substance has a small negative value.
(7) The magnetic susceptibility (χ) of a diamagnetic substance does not change with temperature
