Assertion : In the phenomenon of mutual induction, self induction of each of the coils persists.
Reason : Self induction arises when strength of current in same coil changes. In mutual induction, current is changing in both the individual coils.

The correct Answer is:
a
Mutual inductance is the phenomenon according to which an opposing e.m.f produces flux in a coil as a result of change in current or magentic flux linked with a neighouring coil. But when two emf produced due to mutual induction, also incuded e.m.f is produced in each of the coils are to self-induction.
