Materials and Components - Engineering

Q1:

Assertion (A): Magnetic susceptibility of copper is -0.5 x 10-5. Reason (R): Copper is diamagnetic material.

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

If magnetic susceptibility is very low μ, is nearly equal to 1 and the material is diamagnetic.
