A substance that is weakly attracted when placed in an external magnetic field and does not retain magnetization after the field is removed is classified as :
Paramagnetic
Diamagnetic materials are weakly repelled by a magnetic field, so that option does not describe weak attraction. Ferromagnetic materials are strongly attracted and can retain magnetization even after the field is removed, which also does not match.
Paramagnetic materials have unpaired electrons that align weakly with an external magnetic field, causing weak attraction toward it, but this alignment is not strong enough to persist once the field is removed, so the material loses its induced magnetism.
Therefore, such a substance is classified as paramagnetic.
