Properties of diamagnetic substances are
1) Diamagnetic substances are feebly repelled by a strong magnet.
2) When a bar of a diamagnetic substance is placed in an external magnetic field, the magnetic field lines are repelled by the substance.
3) The relative permeability of a diamagnetic substance is always less than one i.e, μr = <1
4) The magnetic susceptibility of a diamagnetic substance is low and negative value.
5) The magnetic susceptibility of a diamagnetic substance does not change with temperature.
