Vedclass · Answer

(A) The mutual inductance $M$ between two coils depends on the magnetic flux linkage between them. $M$ is directly proportional to the amount of magnetic flux produced by one coil that passes through the area of the second coil. In situation $(A)$,the two coils are placed coaxially with their planes parallel to each other. This configuration allows the maximum number of magnetic field lines produced by the first coil to pass through the second coil,resulting in the maximum flux linkage. In situations $(B)$ and $(C)$,the coils are either perpendicular or at an angle,which significantly reduces the effective flux linkage. Therefore,the mutual inductance is maximum in situation $(A)$.

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