The mutual inductance `M_12` of coil 1 with respect to coil 2

A

increases when they are brought nearer.

B

depends on the current passing through the coils.

C

increases when one of them is rotated about an axis.

D

is the same as `M_21` of coil 2 with respect to coil 1.

Text Solution

Verified by Experts

The correct Answer is:
A, D
Mutual inductance increases when two coils are brought nearer and also `M_12 = M_21`.
Mutual inductance does not depend on current hence, option (B) is incorrect.
