When a diamagnetic material is placed in an external magnetic field the spin motion of electrons is so modified that the electrons which produce the moments in the direction of external field show down while the electrons which produce magnetic moments in opposite direction get accelerated.
Thus, a net magnetic moment is induced in the opposite direction of applied magnetic field. Hence the substance is magnetized opposite of the external field. Thus, it moves from stronger. Weaker parts of the magnetic.
