A current I=20sin(100pit)A is passed in the first coil, which induces a maximum emf of 10piV in the second coil. The mutual inductance for the pair of coils is

A current I=20sin(100pit)A is passed in the first coil, which induces a maximum emf of 10piV in the second coil. The mutual inductance for the pair of coils is

When a current i = 10 sin (100 pi t) A is passed through a coil, an induced emf having a maximum value of 5 pi V is produced in a nearby coil kept parallel to the first coil. What is the mutual inductance between the two coils?

If a current of 3A, flowing in the primary coil is reduced to zero in 10^(-3) s , the induced e.m.f in the secondary coil is 15000 V. The mutual inductance between the two coils is

The current decays from 5A to 2A in 0.01 s in a coil. The emf induced in a coil nearby it is 30V . The mutual inductance between the coils is
