Apentix/AP Physics 2/Unit 5: Magnetism and Electromagnetic Induction/Question

AP Physics 2easymcq1 pt

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

A.Current flows through a wire

B.Magnetic flux through the circuit changes

C.A circuit is at rest in a magnetic field

D.The resistance of the circuit changes

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

BMagnetic flux through the circuit changes
