The Poynting vector represents the direction and magnitude of the flux in energy from an electromagnetic field. It was originally discovered by John Henry Poynting in 1884.
The Main Idea
The poynting vector describes the magnitude and direction of the flux in energy from an electromagnetic field.
A Mathematical Model
The poynting vector can be derived by the equation [math]\displaystyle{ \vec{S} = {\frac{1}{μ_0}}\vec{E}\times\vec{B} }[/math] where E is the electric field vector, and B is the magnetic field vector, and μ0 is the magnetic constant.
