Definitions:

Core Material

The material used in the magnetic core of electrical devices like transformers and inductors, influencing their efficiency and performance.

Electro-magnet

A type of magnet in which the magnetic field is produced by an electric current, usually wrapped around a core of ferromagnetic material, which enhances its magnetic field strength.

Relative Motion

The motion of an object as observed from a particular reference frame, which may be moving or stationary.

Electro-magnetic Induction

Electro-magnetic induction is the process whereby a changing magnetic field within a coil of wire induces a voltage across the ends of the wire, leading to the creation of an electric current.
