What is Faraday's law of electromagnetic induction?

1

Current creates a magnetic field.

2

Magnetic fields always repel each other.

3

A changing magnetic field induces an electromotive force.

4

Electricity and magnetism are unrelated.

Answer and Solution

Answer

C. A changing magnetic field induces an electromotive force.

Solution:

Faraday's law states that a changing magnetic field will induce an electromotive force (EMF) in a conductor, leading to an electric current if the circuit is closed.
