. Assertion In the phenomenon of mutual induction, self-induction of each of the coil persists.

Reason Self-induction arises when strength of current in one coil changes. In mutual induction current is changing in both the individual coils.


Best Answer

Answer : (a)

Solution :The phenomenon of production of emf in a coil when the current in neighbouring coil changes is called mutual induction. The coil in which the current changes is called the primary coil while the neighbouring coil in which emf is induced is called secondary coil. In addition to induced emf which is produced by mutual induction, also the induced emf is produced in each coil because of self-induction.

Hence, option (a) is true.
