Definitions:

Magnetic Poles

The regions at the ends of a magnet where the magnetic field is strongest, designated as north and south poles.

Impedance

The total opposition that a circuit offers to the flow of alternating current, combining resistance and reactance.

Hysteresis

The phenomenon in which the value of a physical property lags behind changes in the effect causing it, often observed in magnetic materials where the magnetic flux density trails the magnetic field strength.

Inductive

Pertaining to inductance or exhibiting properties of inductance, which is the property of an electric conductor or circuit that causes a change in current flow.
