Which law states that the induced electromotive force in a circuit is proportional to the rate of change of magnetic flux?
A. Coulomb's law
B. Faraday's law of electromagnetic induction✓ Correct Answer
C. Ampere's circuital law
D. Lenz's law of conservation
💡 Solution & Explanation
Faraday's law of electromagnetic induction states that the magnitude of the induced electromotive force in a circuit is directly proportional to the time rate of change of magnetic flux linked with that circuit. Alternative principles like Coulomb's law govern electrostatic forces between stationary charges rather than changing magnetic fields. Electromagnetic induction forms the underlying working principle behind modern electrical generators and transformers.
