Faraday's law of electromagnetic induction states that an EMF is induced in a circuit when:

A.Current flows through a wire

B.The resistance of the circuit changes

C.Magnetic flux through the circuit changes

D.A circuit is at rest in a magnetic field

Explanation

Core Concept

Faraday's law states that a changing magnetic flux through a circuit induces an EMF (electromotive force). The magnitude of the induced EMF equals the rate of change of magnetic flux.

Correct Answer

CMagnetic flux through the circuit changes
