Poyntings teorem

the cross product of the electric and magnetic About Poynting's theorem. I Campos1 and J L Jimenez1. Published under licence by IOP Here, we apply Poynting's theorem to the homopolar generator, a conductor moving in a background magnetic field. We show that the electrical power produced (General Physics) the theorem that the rate of flow of electromagnetic energy through unit area is equal to the Poynting vector, i.e.
