AI Customer ServiceFurthermore, additional support provided from the calculations using the Biot–Savart law which show that the magnetic field between the capacitor plate is actually created by the real currents alone have only recently been reported. This late confirmation may have been another factor which allowed the misconception to persist for a long time.
Bartlett [ 11] made an analytical calculation of the magnetic field between the capacitor plates to show with some approximation that it is actually created by the linear current in the lead wire and the radial current in the plates. Milsom [ 12] provided numerical results together with an excellent compact review of the topic.
Since the capacitor plates are charging, the electric field between the two plates will be increasing and thus create a curly magnetic field. We will think about two cases: one that looks at the magnetic field inside the capacitor and one that looks at the magnetic field outside the capacitor.
More recent articles include reference [ 22 ]. All these experiments, and likely many other reports on this topic, take it for granted that the displacement current density, or time derivative of the electric field multiplied by ɛ0, ɛ0E /∂ t, in the space between the electrodes of a capacitor creates the magnetic field in and around it.
From that it follows that the steady-state capacitance should be identical to that of the same capacitor outside the field. Or at least it would follow for a capacitor with vacuum between the plates. If there is a dielectric involved it we could at ask if the presence of the magnetic field has any effect on the dielectric constant of that material.
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.
