👉 Poynting is a mathematical concept in the field of electromagnetism. It describes the flux of electric and magnetic fields through a closed surface, which can be used to calculate the total energy of an electromagnetic system. In simple terms, poynting refers to the flow of electric and magnetic fields perpendicular to each other inside or on the surface of an object (like a conductor). This flow is often represented by a vector field called the Poynting Vector. The Poynt
