Materials and Components - Engineering

Q1:

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

ANS:A - Both A and R are true and R is correct explanation of A

Magnetic susceptibility = (μr - 1)H. For diamagnetic and paramagnetic materials magnetic susceptibility is very very small and μr = 1.
