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

A

Maximum in situation `(A)`

B

Maximum in situation `(B)`

C

Maximum in situation `(C)`

D

The same in all situations

Text Solution

Verified by Experts

The correct Answer is:
A
The mutual inductance between two coils depends on their degree of flux linkage, i.e., the fraction of flux linked with one coil which is also linked to the other coil. Here, the two coils in arrangement (a) are placed with their planed parallel. This will allow maximum flux linkage.
