Poynting Vector Formula

Poynting Vector represents the direction of energy-flux density in an electromagnetic field

Poynting Vector formula is represented by

Poynting Vector Formula 1
Poynting Vector Formula 2
Where,

S = Poynting Vector

E = Electric Field

B = Magnetic Field

μ 0= vacuum permeability = 1.257 x 10 6 henry/ meter

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