With alternating current, the north and south poles of the magnetic field surrounding the wire change each time the electrons change direction.

Question

Quizplus · Accepted Answer

In alternating current (AC), the direction of the electron flow reverses periodically, which also causes the direction of the magnetic field to reverse, thus changing the north and south poles of the magnetic field surrounding the wire.

With Alternating Current, the North and South Poles of the Magnetic
