چکیده
The related issue of the flow of energy in such circuits as described by the Poynting vector is considered in [1]. Supposing the distance d between the centers of the two coils is small compared to the wavelength λ = 2πc/ω, where c is the speed of light in vacuum, circuit analysis is a good approximation. Writing the self inductance of the two coils as Lp = Ls = L and their mutual inductance asM(d), the circuit equations are (for time dependence e for the voltage source)
