What occurs when an electric current flows through a coil of wire?

Back

A magnetic field is created around the coil.

Front

What happens to the magnetic field when the electric current is turned off?

Back

The magnetic field suddenly disappears.

What is the role of a coil of wire in motors and generators?

Back

In both motors and generators, a coil of wire is placed in a magnetic field to either produce motion (motor) or generate electricity (generator).
