Vedclass · Answer

(B) diamagnetic substance is characterized by a negative magnetic susceptibility $(\chi When placed in an external magnetic field $(B_0)$, the substance develops an induced magnetic moment in the direction opposite to the applied field.This results in the internal magnetic field $(B)$ being weaker than the external field $(B_0)$.Mathematically, $B = \mu_0(H + M)$, where $M$ is the magnetization. Since $M$ is negative for diamagnetic materials, the net magnetic induction inside the substance decreases compared to the external field.

When a diamagnetic substance is placed in a magnetic field, the magnetic induction inside the substance :-
