KnowraPoynting vectorLinked fromLinked fromThe 8 pages that link to Poynting vector, each with the reason it gives.All 8Related 6Compared with 2Magnetic fluxCompared with: It measures energy transport, whereas magnetic flux measures magnetic field through area.Electromagnetic fieldRelated: It quantifies energy carried by the field, including by waves.Displacement currentRelated: Displacement current participates in field configurations that transport energy through space.Wave vectorCompared with: It describes energy transport, which need not point along the wave vector in every medium.Larmor formulaRelated: Integrating its outward flux gives the radiated power in the formula.Negative-index metamaterialRelated: It distinguishes energy transport from the oppositely directed phase progression.Impedance of free spaceRelated: The vacuum impedance converts between field amplitudes when calculating a wave’s energy flux.Poynting's theoremRelated: The theorem uses this flux, but the vector alone does not state the full energy balance.
