The near field is remarkable for reproducing classical electromagnetic induction and electric charge effects on the EM field, which effects "die-out" with increasing distance from the antenna: The magnetic field component that’s in phase quadrature to electric fields is proportional to the inverse-cube of the distance () and electric field strength proportional to inverse-square of distance (). This fall-off is far more rapid than the classical "radiated" far-field ( and fields, which are proportional to the simple inverse-distance (). Typically near-field effects are not important farther away than a few wavelengths of the antenna.
