Question
Magnitude of induced e.m.f is proportional to
Correct Answer
Option C is the correct answer.
Detailed Explanation
Faraday's law of electromagnetic induction states that the magnitude of the induced electromotive force (e.m.f) in a circuit is directly proportional to the rate of change of magnetic flux linkage through the circuit (ε = -N dΦ/dt).
Hint
Recall Faraday's Law of Induction, which describes how a changing magnetic field creates an e.m.f.
