Variable	Description	Unit variables	Units
$\vec{E}$	Electric Field Intensity	$V / m$ or $N / C$	Volts per Meter or Newtons per Coulomb
$\vec{D}$	Electric Flux Density	$C / m^{2}$	Coulombs per Meter squared
$\vec{H}$	Magnetic Flux Intensity	$A / m$	Amps per Meter
$\vec{B}$	Magnetic Flux Density or Magnetic Induction	$T$ or $W / m^{2}$ or $G$	Tessla or Watts per meter squared or Gauss'

Relationships

$\vec{D} = \in \vec{E}$

In free space:

$\in_{0} = 1 / (36 * π) * 1 0^{- 9}$ F/m

$\vec{B} = μ \vec{H}$

In free space:

$μ_{0} = 4 * π * 1 0^{- 7}$ H/m
