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

The Correct Option is C
Solution and Explanation
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 magnetic flux linked with a neighbouring coil. But when two coils are inductively coupled, in addition to induced e.m.f. produced due to mutual induction, also induced e.m.f. is produced in each of the two coils due to self-induction.

Electromagnetic Induction
Electromagnetic Induction is a current produced by the voltage production due to a changing magnetic field. This happens in one of the two conditions:-
- When we place the conductor in a changing magnetic field.
- When the conductor constantly moves in a stationary field.
Formula:
The electromagnetic induction is mathematically represented as:-
e=N × d∅.dt
Where
- e = induced voltage
- N = number of turns in the coil
- Φ = Magnetic flux (This is the amount of magnetic field present on the surface)
- t = time
