Definitions:

Induced Voltage

Voltage generated in a conductor or coil due to a change in magnetic flux, according to Faraday's law of electromagnetic induction.

Eddy Current

Circular induced current contrary to the main currents. Eddy currents are a source of heat and power loss in magnetically operated devices.

Hysteresis

The phenomenon in which the state of a material lags behind changes in the effect causing it, such as the lagging of magnetic flux density behind the magnetizing force.

Spike Suppression

Techniques or devices used to protect electronic circuits from sudden transient voltages, which could cause damage or malfunction.
