Magnetic Flux Density

(B, Magnetic Field, Magnetic Induction, B Field)
(vector field describing magnetism in relation to the Lorentz force)

The Magnetic Flux Density (Magnetic Field, Magnetic Induction, B Field, or B) is a vector field describing magnetic forces in a volume. Its relationship to an electric field (E) is defined by Maxwell's Equations and is illustrated by the Lorentz Force Law:

F = q(E + v x B)
  • F - force on a particle.
  • q - electric charge of the particle.
  • E - electric field.
  • v - velocity of the particle.
  • B - Magnetic Flux Density.

The unit is the Tesla (SI) or Gauss (CGS).
