1
New cards

Conductor

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

2
New cards

Insulator

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

3
New cards

Ferromagnetic materials

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

4
New cards

Flux density

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

5
New cards

Weber

The SI unit of magnetic flux.

6
New cards

Tesla

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

7
New cards

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.

8
New cards

Permeability

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

9
New cards

Reluctance

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

10
New cards

Magnetomotive force (MMF)

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

11
New cards

Solenoid

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

12
New cards

Gauss

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

13
New cards

Electromagnetic induction

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

14
New cards

Magnetic flux

The total magnetic field that passes through a given area.

15
New cards

Coil

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

16
New cards

Current flow

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

17
New cards

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.
