Poynting Vector Formula

Poynting vector formula is represented by

\(\underset{S}{\rightarrow} = \frac{1}{\mu}\underset{E}{\rightarrow}\times \underset{B}{\rightarrow}\)

Where,

S = Poynting Vector

E = Electric Field

B = Magnetic Field

\(\mu _{0} = Vacuum\,Permeability\)

Poynting Vector is the cross product of electric and magnetic fields.
