Materials that are referred to when discussing paramagnetism are aluminum or platinum.

if a strong magnetic field is applied, the molecular magnets set themselves with their lengths almost parallel to it. thus when the resultant magnetic effect is weak,the process is called paramagnetism

paramagnetism is foung in aluminium,manganese and platinum.

Gallium is diamagnetic.

Note Unlike all the other members of group 13 aluminium exhibits a form of paramagnetism called "Pauli paramagnetism".

give Langevins theory of paramagnetism?
