NettetEquation (3) gives the expression for the energy density of an electromagnetic wave, where 𝜇 0 is the permeability of free space and 𝜺 0 is the permittivity of free space. The unit of energy density is Joule/m 3: Expressing Energy Density in Terms of Either the Electric Field or Magnetic Field NettetAt first the concept of a field might seem abstract, but a field is really just a mathematical construct. An electric field is a vector field that assigns each point in space a vector indicating the force per unit charge at that location. …
