induced current  Movement of a magnet in a coil of wire induces a current. | Electric current that appears in a closed circuit when there is relative movement of its conductor in a magnetic field. The effect is known as the dynamo effect, and is used in all dynamos and generators to produce electricity. See electromagnetic induction. |
| The magnitude of the induced current depends upon the rate at which the magnetic flux is cut by the conductor, and its direction is given by Fleming's right-hand rule (see Fleming's rules). |
