Definition: Electro-magnet is an electrical system used to transfer a magnetic field or a current from one point to another through electrical circuits. The word Electro-magnet is a technical term that describes various components, systems, devices, or processes in which electricity can be used as a medium for transferring magnetic fields or currents. These include transformers and inverters, electromagnets, AC generators, DC motors, and DC generators. In general, an electro-magnet refers to any electrical circuit, device, or system that uses magnets to transfer a current. It can be used to generate power, amplify signals, or control the flow of electricity in various applications.

Definition: Electro-magnetic interaction, known as magnetism, occurs when electric currents cause an induced magnetic field around a stationary charged body or system. It can be described in several ways: 1.

Electricity:

The presence of electrical current means that there is a movement of electric charge through the material between its poles. This movement produces a magnetic field, which opposes the direction of the electric current. 2.

Field:

In magnetism, the strength and direction of the magnetic field are controlled by the magnitude and polarity of the electric currents. The force exerted on an object due to this field is called electromotive force (EMF). 3.

Electric Current:

Electrically induced currents can be either steady or time-dependent. The electric current is proportional to the change in potential energy between two points that are separated by a distance, and it depends on the applied voltage. 4.

Electromagnetic Field:

The magnitude of the magnetic field produced by an electric current is determined by the direction of the current and its strength, which depend on both the source (source of the electric current) and the target material being magnetized. 5.

Magnetization:

This term describes a phenomenon where electrons are attracted to each other in an attractive or repulsive magnetic field. Magnetization can be achieved through heating, external sources, or by using magnets. 6.

Magnetic Field Strength:

The strength of the magnetic field produced by an electric current is measured in tesla (T), and it's typically between zero and infinity, depending on the direction of the applied voltage and the material properties. 7.

Electromagnetism:

This term refers to the scientific branch that deals with the phenomena and processes occurring when electric currents cause changes in magnetic fields. 8.

Magnetic Field Strength Measurement Systems:

These include current transformers (CTPs), which can measure the magnitude of a current's magnetic field, and transformers like the electromotive force (EMF) transformer, which can measure the EMF produced by an applied voltage.
