NEET Physics Self & Mutual Induction MCQ Question
Which combination of statements about self-induction and mutual induction is correct?
Self-induction occurs in a single coil due to its own changing current; mutual induction occurs between two coils with a changing current in one affecting the other.
Mutual induction only occurs when both coils have the same number of turns; self-induction can occur in any coil regardless of its turns.
Self-induction induces an emf that supports the change in current; mutual induction's emf always opposes the change in current.
Self-induction is independent of the rate of change of current; mutual induction does not depend on the distance between coils.
Correct Answer
Detailed Explanation
Self-induction is defined as the emf induced in a single coil due to its own changing current, while mutual induction refers to the emf induced in a neighboring coil due to a changing current in another coil, as described in the provided context.
