Definition

Magnetic flux density is the force exerted on a test charge perpendicular to its velocity through a magnetic field.

Hence it is a measure of the intensity of that magnetic field.


Symbol

The usual symbol used to denote magnetic flux density is $\mathbf B$.


Dimension

Magnetic flux density has the dimension $\mathsf {M T^{-2} I^{-1} }$.


Units

The SI unit of magnetic flux density is the tesla $\mathrm T$.

In the CGS unrationalised electromagnetic system, the unit of magnetic flux density is the gauss $\mathrm {Gs}$.


Conversion Factors

\(\ds \) \(\) \(\ds 1\) tesla
\(\ds \) \(=\) \(\ds 10^4\) gauss (or e.m.u. of magnetic flux density)
\(\ds \) \(\approx\) \(\ds \dfrac 1 3 \times 10^{-6}\) e.s.u. of magnetic flux density
