\begin{definition}[Definition:Magnetic Field Strength]
'''Magnetic field strength''' is the measure of the intensity of a magnetic field.
It can be expressed as:
:$\mathbf H = \dfrac {\mathbf B} \mu$
where:
:$\mathbf B$ is the magnetic flux density
:$\mu$ is the permeability of the medium.
It is a vector quantity.
