The coefficient of mutual induction between two circuits is equal to the, emf produced in one circuit when the current in the second circuit is

When is emf induced in a circuit ?

In a purely inductive circuit, the current is

In a purely inductive circuit, the current

Two circuits have mutual inductance of 0.1 H . What average e.m.f. is induced in one circuit when the current in the other circuit changes from 0 to 20 A in 0.02 s

The coefficient of mutual inductance of two coils is 10 mH. IF the current flowing in one coil is 4A then the induced e.m.f in the second coil will be

The current flows in a circuit as shown below . If a second circuit is brought near the first circuit then the current in the second circuit will be :-
