Two circular coils can be arranged in any of the three situations shown in the figure. Their mutual inductance will be ____
Open in App
Solution
The correct option is C maximum in situation (A).
Mutual Induction is the phenomenon of an emf being induced in one coil in response to current changing in another coil.
The mutual inductance between two coils depends on their degree of flux linkage, i.e., the fraction of flux of one coil linked to the other coil. When two coils are placed close to each other, then the mutual inductance of the pair of coils depends upon relative position and orientation of the two coils. Here, the two coils in arrangement (A) are placed with their planes parallel. This will allow maximum flux linkage. So, the mutual inductance will be maximum in (A).
