Two circular coils can be arranged in any of the three situations shown in the figure. Their mutual inductance will be [2001]

Question

Smart Achievers · Accepted Answer

(1)

When current flows in any of the coils, the flux linked with the other coil is maximum when surface area to receive flux is maximum. Clearly the flux linkage is maximum in case (1) due to the spatial arrangement of the two circular coils.

Solution
