Definitions:

Magnetic Polarity

Refers to the orientation of the magnetic poles in a magnet, determining the direction of the magnetic field's flow.

Electromagnet

A type of magnet where the magnetic field is produced by an electric current, typically involving a wire coil.

Volts-per-turn Principle

The volts-per-turn principle relates to the design of electromagnetic coils, stating that the induced voltage in a coil is proportional to the rate of change of magnetic flux linkage per turn of the coil.

Electro-magnetic Induction

A phenomenon where an electric current is induced in a conductor when it is exposed to a changing magnetic field.
