Assertion (A): Magnetic susceptibility of diamagnetic materials is much less than that of paramagnetic materials. Reason (R): For diamagnetic as well as paramagnetic materials, μr is nearly equal to 1.
Correct Answer: Both A and R are true and R is correct explanation of A
Explanation:
Magnetic susceptibility = (μr - 1)H.
For diamagnetic and paramagnetic materials magnetic susceptibility is very very small and μr = 1.
