Using Maxwell's Equations. The electric field intensity for a wave propagating away from a point-like source is given in phasor form as: -jR o a) Use the differential form of Faraday's induction Law to determine the corresponding magnetic field intensity associated with this electric field. b) Show that the time average power density (the time average Poynting vector) flows radial away from the point source and falls off as 1/R. (R) = Vo R
