Transformer |
Device for increasing or decreasing voltage or transferring electric power from one coil of wire to another by means of electromagnetic induction. |
|
|
Faradays Law |
Induced vintage in a coil is proportional to the product of the number of loops and the rate at which the magnetic field charges within those loops. In general, an electric field is induced in any region of space in which a magnetic field is changing with time. The magnitude of the induced electric field is proportional to the rate at which the magnetic field charges. (2 words) |

Generator |
Machine that produces electric current usually by rotating a coil within a stationary magnetic field. |
|
|
Electromagnetic induction |
Phenomena of inducing a voltage in a conductor by changing the magnetic field near the conductor. If the magnetic field near the loop changes in any way, a voltage is induced in the loop. The induction of voltage is actually the result of a more fundamental phenomenon: the induction of an electric field. (2 words) |

Maxwell's counterpart |
(- to Faradays Law) a magnetic field is created in any region of space in which an electric field is changing with time. The magnitude of the induced magnetic field is proportional to the rate at which the electric field changes the direction of the induced magnetic field is at right angles to the changing electric field.
