Question
Assertion (A): Magnetic susceptibility of diamagnetic materials is much less than that of paramagnetic materials.
Reason (R): For diamagnetic as well as paramagnetic materials, ?_r is nearly equal to 1.
Options
A. Both A and R are true and R is correct explanation of A
B. Both A and R are true but R is not correct explanation of A
C. A is true but R is false
D. A is false but R is true

Correct Answer

Both A and R are true and R is correct explanation of A

Explanation

Magnetic susceptibility = (?_r - 1)H.

For diamagnetic and paramagnetic materials magnetic susceptibility is very very small and ?_r = 1.
