Definitions:

Time Constant

The amount of time required for the current flow through an inductor or for the voltage applied to a capacitor to reach 63.2% of its total value.

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.
