What Is Eddy Current?

Answer

An Eddy current in when electricity spins on a piece of metal. Basically it spins in circles, because it is caught in a magnetic force that it can not get past.

What Are Eddy Currents?
Just as turbulence forms when a body moves through air, when a magnetic field is found to be changing close to a conductor, eddy currents form within the conductor. These currents form a mechanism of loss for devices that operate with magnetic fields,... More »

Eddy current, also known as Foucault current, is an electrical phenomenon discovered by Francois Arago in 1824. It is caused when a conductor is exposed to a changing magnetic field caused by relative motion of the field source and conductor; or because of variations of the field with time.
