A substance, when inserted between the poles of a magnet, is pushed out, what is it?
Magnetic substance when kept in a magnetic field is feebly repelled or thrown out if the substance is diamagnetic. This happens because the substance is feebly magnetised in the direction opposite to that of the field. The susceptability of diamagnetic substance is negative. Paramagnetic substances are feebly attracted by a magnetic. Ferromagnetic substances are strongly attracted by a magnet.
