Conductor

A material that allows electricity or magnetism to pass through it without hindrance.

Insulator

A material that resists the flow of electric current or magnetic fields.

Ferromagnetic materials

Materials such as iron, nickel, and cobalt that can be magnetized and retain magnetism.

Flux density

The measure of the strength of a magnetic field per unit area, expressed in Weber per square meter (Tesla).

Weber

The SI unit of magnetic flux.

Tesla

The unit used to measure the strength of a magnetic field.

Hall effect

The production of a voltage difference (Hall voltage) across an electrical conductor when a magnetic field is applied perpendicularly to the current flow.

Permeability

The degree to which a material can support the formation of a magnetic field within itself.

Reluctance

The opposition to the establishment of a magnetic field in a material, analogous to resistance in electric circuits.

Magnetomotive force (MMF)

The potential that drives magnetic flux through a magnetic circuit, measured in amperes per turn.

Solenoid

A coil of wire that generates a magnetic field when electric current flows through it.

Gauss

The unit of measurement for the strength of a magnetic field, notably smaller than a Tesla.

Electromagnetic induction

The process of generating electric current from the motion of a conductor through a magnetic field.

Magnetic flux

The total magnetic field that passes through a given area.

Coil

A wire wound in a spiral or spiral-like shape, often used in electromagnets.

Current flow

The movement of electric charge carriers, usually electrons, through a conductor.

Faraday's law of induction

A principle stating that a change in magnetic field within a closed loop induces an electromotive force (EMF) in the loop.
