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).
