Two circular coils can be arranged in any of the three situation shown in the figure. Their mutual inductance will be
, ,

A

(A) maximum in situration (a)

B

(B) maximum in situration (b)

C

maximum in situtaion (c )

D

the same in all situations

Verified by Experts

The correct Answer is:

A

The mutal inductance between the two coil in orientation `(A)` is the maximum since the flux linkage in `(A)` is the maximum as shown in the figure.
