The mutual inductance of a pair of coils, each of N turns, is M henry. If a current of I ampere in one of the coils is brought to zero in t second, the emf induced per turn in the other coil, in volt, will be??

Answer:
Nt
Mi
Induced emf = Mutual Inductance ×
dt
di
e=M
dt
di
In given problem, for N turns,
e=M
t
i
So, induced emf per turn in the coil is Mi/Nt.
