2012-11-20 · This theorem states that the cross product of electric field vector, E and magnetic field vector, H at any point is a measure of the rate of flow of electromagnetic energy per unit area at that point, that is P = E x H Here P → Poynting vector and it is named after its discoverer, J.H. Poynting.
