Which specific law states that the magnitude of the induced emf in a circuit is equal to the rate of change of magnetic flux through the circuit?

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

💡 Solution & Explanation

Faraday's law of electromagnetic induction states that the magnitude of the induced electromotive force in a circuit equals the rate of change of magnetic flux linking the circuit. Lenz's law specifies the direction of the induced current to oppose the change producing it, while Ampere's law relates magnetic fields to electric currents. Biot-Savart law calculates the magnetic field generated by a steady electric current.
