Question

Draw magnetic field lines when (a) (i) diamagnetic ,(ii) paramagnetic substance is placed in an external magnetic field. Which magnetic property distinguishes this behaviour of the field lines due to the two substances ?

Answer 1

(i) Behaviour of magnetic field lines when a diamagnetic substance is placed in an external field.
(ii) Behaviour of magnetic field lines when a paramagnetic is placed in an external field.
Magnetic suscepilibility distinguishes this behaviour of the field lines due to diamagnetic and paramagnetic substances.
