Explain Eddy Currents.

An eddy current is a circular current that flows in a solid conductor, such as sheets of metal or rods. When a changing magnetic field is somehow applied to such a conductor, electromagnetic induction occurs. However, since the charges are not bounded by a narrow conductor, the currents flow in circles called eddy currents. The eddy current flows in a closed loop and acts like the current in a coil or solenoid that produces its own magnetic field.
