Vectors (mathematics and physics)
In physics, the Poynting vector (or Umov–Poynting vector) represents the directional energy flux (the energy transfer per unit area per unit time) or power flow of an electromagnetic field. The SI unit of the Poynting vector is the watt per square metre (W/m2); kg/s3 in base SI units. It is named after its discoverer John Henry Poynting who first derived it in 1884. Nikolay Umov is also credited with formulating the concept. Oliver Heaviside also discovered it independently in the more general form that recognises the freedom of adding the curl of an arbitrary vector field to the definition. The Poynting vector is used throughout electromagnetics in conjunction with Poynting's theorem, the continuity equation expressing conservation of electromagnetic energy, to calculate the power flow in electromagnetic fields.

Circuit Energy doesn't FLOW the way you THINK!
Based on the laws of electrodynamics, energy cannot flow in the same direction as the electric current. According to the Poynting vector, electric power will flow anywhere there is both an electric field and a magnetic field. The consequences may surprise you. _____________________________
