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
throughout 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 × B)
- F - force on a particle.
- q - electric charge of the particle.
- E - electric field.
- v - velocity of the particle.
- B - magnetic flux density.
- × - vector cross product.
Its measurement unit is the tesla (SI) or gauss (CGS).
Another measure of magnetism is the magnetic field strength (H). The physical quantities
(B and H) are equivalent for the portion of a magnetic
field in a vacuum, but differ where the magnetic field is passing
through some material.
