Question

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.
A. If both Assertion and Reason are corrent and Reason is the corrent explanation of Assertion.
B. If both Assertion and Reason are correct but Reason is not the correct explanation of Assertion.
C. If Assertion is true but Reason is false.
D. If Assertion is false but Reason is ture.

Answer 1

Correct Answer - B
The total number of magnetic lines of force passing through an area placed in magnetic field is equal to magnetic flux linked with the area.
Mutual inductance is the phenomenon according to which on opposing emf produces. Flux in a coil as a result of change in the current or magnetic flux linked with neighbouring coil. But when two coils are coupled, in emf produced inductively addition to induced due to mutual inductance, induced emf is also produced in each of the two coils due to self-inductance.
