Vedclass · Answer

(A) The mutual inductance $M$ between two coils depends on the magnetic flux linkage between them. The flux linkage is maximum when the magnetic field lines produced by one coil pass through the area of the other coil most effectively.In situation $(A)$,the planes of the two coils are parallel to each other. This orientation allows the maximum number of magnetic field lines produced by the larger coil to pass through the area of the smaller coil,resulting in the maximum magnetic flux linkage.In situation $(B)$,the smaller coil is placed perpendicular to the plane of the larger coil. In this case,the magnetic field lines from the larger coil are mostly parallel to the plane of the smaller coil,resulting in minimal flux linkage.In situation $(C)$,the smaller coil is placed in the same plane as the larger coil but shifted to the side. This also results in a lower flux linkage compared to situation $(A)$.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
