Two characteristic properties distinguishing paramagnetic and diamagnetic materials are:
(i) Diamagnetic substances move from stronger to weaker regions of a non-uniform magnetic field, whereas paramagnetic substances move from weaker to stronger regions.
(ii) When placed in an external magnetic field, diamagnetic materials expel magnetic field lines, weakening the field inside. In contrast, paramagnetic materials allow the field lines to concentrate, slightly enhancing the magnetic field inside.
