AIIMS 2018 Physics Mutual Inductance MCQ Question
Assertion : In the phenomenon of mutual induction, self induction of each of the coil persists.
Reason :Self induction arises due to change in current in the coil itself. In mutual induction current changes in both the individual coil.
If both assertion and reason are true and reason is the correct explanation of assertion.Option A
If both assertion and reason are true but reason is not the correct explanation of assertion.Option B
Option CIf assertion is true but reason is false.
Option DIf both assertion and reason are false
Correct Answer
Detailed Explanation
Option B is correct because it accurately describes the phenomenon of mutual inductance, which occurs when a change in current in one coil induces an electromotive force (e.m.f.) in a neighboring coil due to the magnetic flux linkage. Additionally, each coil experiences self-induction, where a change in its own current generates an opposing e.m.f. due to its own magnetic field. Other options may misrepresent the relationship between mutual and self-induction or fail to acknowledge the simultaneous effects of both phenomena in coupled coils, leading to an incomplete understanding of inductive coupling. Understanding these concepts is crucial for analyzing circuits involving inductors and transformers.
