The coefficient of mutual inductance

In a transformer , the coefficient of mutual inductance between the primary and the secondary coil is 0.2 henry. When the current changes by 5 ampere//second in the primary, the induced e.m.f. in the secondary will be

A current of 10A in the primary coil of a circuit is reduced to zero. If the coefficient of mutual inductance is 3 H and emf induced in the secondary coil is 30 kV, time taken for the change of current is
