Assertion (A): Magnetic susceptibility of diamagnetic materials is much less than that of paramagnetic materials. Reason (R): For diamagnetic as well as paramagnetic materials, Î¼r is nearly equal to 1.

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.

[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

Answer: Option A

Explanation:

Magnetic susceptibility = (μr - 1)H.

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