Recall / Warm-Up

Which of the following is required to induce an EMF in a conducting loop?

A strong, uniform magnetic field through the loop.

A change in the magnetic flux through the loop.

A current flowing in the loop before induction begins.

The loop must be moving — stationary loops cannot experience induction.
