Magnetic flux density
The magnetic flux density B is a measure of the strength of the magnetic field under the influence of matter.
Explanation
The magnetic induction in a point is the magnetic flux per unit area. It is a vector quantity that plays a role in electromagnetic field theory.
Example 1
The Maxwell equation of the magnetic flux density is

where
µ0 Magnetic constant H Magnetic field M Magnetization
Example 2
The magnetic field occurs in the Lorentz force
where
q Electric charge E Electric field v Velocity × Cross product B Magnetic field
HistoryThe unit of magnetic flux density is expressed in Tesla, and is named after the Serbo-Croatian-American inventor Nikola Tesla (1856 - 1943). |
