Question

Quizplus · Accepted Answer

Voltage can be induced in a wire through electromagnetic induction, which occurs when there is a change in the magnetic environment of the wire. This can happen by changing the current in a nearby wire (which changes the magnetic field around the first wire), moving a magnet near the wire, or moving the wire through a magnetic field (such as moving the wire near a magnet). All these actions change the magnetic flux through the wire, inducing a voltage.
