# 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.
