Reference Terms and Units

This article is for the conference on Monday January 11

Variable	Description	Unit variables	Units
${\vec {E}}$	Electric Field Intensity	$V/m\,\!{\text{ or }}N/C\,\!$	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	$T\,\!{\text{ or }}Wb/m^{2}\,\!{\text{ or }}G\,\!$	Tesla or Webers per Meter squared or Gauss

Relationships

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

• In free space:

• $\epsilon _{0}={\frac {1}{36\pi }}\times 10^{-9}\ \ F/m$

${\vec {B}}=\mu {\vec {H}}$

• In free space:

• $\mu _{0}=4\pi \times 10^{-7}\ \ H/m$
