| Assertion: In the phenomenon of mutual induction, self-induction of each of the coils persists. |
| Reason: Self-inductance arises when strength of current in one coil changes. In mutual induction, current is changing in both the individual coils. |
A) If both assertion and reason are true and reason is the correct explanation of assertion.
B) If both assertion and reason are true and reason is not the correct explanation of assertion.
C) if assertion is true but reason is false.
D) If both assertion and reason are false.
E) If assertion is false but reason is true.
Correct Answer: A
Solution :
Mutual inductance is the pehnomenon according to which an opposing e.m.f. produce 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 induce e.m.f. produce due to mutual induction, also induced e.m.f. is produced in each of the two coils due to self-induction.
