A magnetic loop behaves electrically as a coil behaves electrically as a coil (inductor) with a small but non-negligible radiation resistance due to its finite size. It can be analyzed as coupling directly to the be analyzed as coupling directly to the magnetic field opposite to the principle of a Hertzian dipole which couples directly to the electric field in the near field, which itself is coupled to an electromagnetic wave in the far field through the application of Maxwell’s equations Maxwell’s equations.
