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 tesla (symbol T) is the SI derived unit of magnetic flux density.
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

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