Question

Quizplus · Accepted Answer

When a magnet is thrust into a coil of wire, it induces a current in the wire. This current creates a magnetic field around the wire. The direction of the magnetic field depends on the direction of the current. Therefore, the coil becomes an electromagnet because it produces a magnetic field when there is a current flowing through it.
