MAGNETISM

WHAT IS MAGNETISM?

Magnetism is a force of attraction or repulsion that

acts at a distance.

A magnetic field consists of imaginary lines of flux coming from moving or

spinning electrically charged particles.

Examples include the spin of a

proton and the motion of

electrons through a wire in an

electric circuit.

Every material is influenced to some extent by a magnetic

field.It is more inherent in magnetic

objects such as a magnet.

Quantity of MagnetismMagnetomotive Force

Strength or force of a magnetic field, or

“push.”

Quantity of MagnetismField Flux

Total field effect or substance.

Quantity of MagnetismField Intensity

Amount of field force distributed over the lengths of the electromagnet.

Quantity of MagnetismFlux Density

Amount of magnetic field flux concentrated in a given area.

Quantity of MagnetismPermeability

Acceptance of magnetic flux of a material.

Quantity of MagnetismReluctance

Opposition to magnetic

field flux
