Write three properties of paramagnetic substance.

Explanation

(i) When placed in -a non-unifrom magnetic field, a piece of paramagnetic substance will tend to move from weak field to strong field. i.e., they get weakly attracted to a magnet.
(ii) They get weakly magnetised when placed in an external magnetic field.
(iii) The individual atoms (or ions or molecules) of a paramagnetic material possess a permanent magnetic dipole moment of their own.
(iv) Paramagnetic substances do not possess net magnetisation.
(v) The magnetisation of a paramagnetic material is inversely proportional to the absolute temperature T.
(vi) X is small and positive for paramagnetic materials.
