WebNov 22, 2013 · time per unit area). Intuitively, if one pictures the probability density as an inhomogeneous fluid, then the probability current is the rate of flow of this fluid. This is analogous to mass currents in hydrodynamics and electric currents in electromagnetism. It is a real vector, like electric current density. The notion of a probability current is WebApr 14, 2024 · The Poynting vector is the term used to characterize electromagnetic energy density. The propagation of electromagnetic energy in a path normal to the directions of the electric and magnetic fields is described as this physical quantity . The Poynting vector is denoted mathematically as: thomas fuckner grasellenbach
