An example illustrating the need for the displacement current arises in connection with capacitors with no medium between the plates. Consider the charging capacitor in the figure. The capacitor is in a circuit that transfers charge (on a wire external to the capacitor) from the left plate to the right plate, charging the capacitor and increasing the electric …

A typical case of contention is whether the magnetic field in and around the space between the electrodes of a parallel-plate capacitor is created by the displacement current density in the space. History of the controversy was summarized by Roche [ 1 ], with arguments that followed [ 2 – 4 ] showing the subtlety of the issue.
