About Magnetic Flux Density
Magnetic flux density (B), also called magnetic induction, is a measure of the strength of a magnetic field. It is measured in tesla (T) in the SI system and gauss (G) in the CGS system. Unlike magnetic field strength, flux density depends on the material properties of the medium.

Lorentz Force
Magnetic flux density determines the force on moving charges through the Lorentz force equation: F = q(v × B), where q is the charge, v is velocity, and B is the flux density. This fundamental relationship governs the operation of electric motors, generators, and particle accelerators.
