Which physical law states that the magnitude of the induced electromotive force in a closed circuit is directly proportional to the time rate of change of magnetic flux linked with the circuit?
A. Ampere circuital law
B. Faraday law of electromagnetic induction✓ Correct Answer
C. Biot-Savart law
D. Lenz law of polarity
💡 Solution & Explanation
Faraday law of electromagnetic induction quantifies how changing magnetic fields generate electrical voltage in conducting loops. Lenz law provides the negative sign indicating the direction of the induced current to oppose the flux change. Ampere law relates magnetic fields to electric current enclosing them.
