Which law of electromagnetic induction states that the induced electromotive force in any closed circuit is equal to the rate of change of the magnetic flux linking the circuit?

A. Coulomb's law
B. Ampere's circuital law
C. Faraday's law✓ Correct Answer
D. Biot-Savart law

💡 Solution & Explanation

Faraday's law of electromagnetic induction establishes that the magnitude of the induced electromotive force in a circuit is directly proportional to the rate of change of magnetic flux linked with that circuit. Other laws like Coulomb's law and Ampere's circuital law deal with electrostatic forces and magnetic fields produced by electric currents respectively. This principle forms the foundational operating mechanism for electrical generators and transformers.
