Two circular coils can be arranged in any of the three situations shown in the figure. Their mutual inductance will be
Maximum in situation $(A)$
Maximum in situation $(B)$
Maximum in situation $(C)$
The same in all situations
Two conducting circular loops of radii $R_1$ and $R_2$ are placed in the same plane with their centre coinciding. If $R_1 >> R_2$ the mutual inductance $M$ between them will be directly proportional to
$AB$ is an infinitely long wire placed in the plane of rectangular coil of dimensions as shown in the figure. Calculate the mutual inductance of wire $AB$ and coil $PQRS$
The mutual inductance between the rectangular loop and the long straight wire as shown in figure is $M$.
An $e.m.f.$ of $100\,millivolts$ is induced in a coil when the current in another nearby coil becomes $10\, ampere$ from zero in $0.1\,second$ . The coefficient of mutual induction between the two coils will be.....$millihenry$
