The reason for the introduction of the ''displacement current'' was exactly to solve cases like that of a capacitor. A magnetic field cannot have discontinuities, unlike the electric field (there are electric charges, but there are not magnetic monopoles, at least as far as we know in the Universe in its current state). ...

Circular Loop & Magnetic Field: Solving for Charge Q
In summary, the conversation discusses a setup with a circular loop containing a capacitor and resistor placed in a uniform magnetic field that decreases at a constant rate. The charge on the capacitor when it is fully charged is given by Q = Cepsilon = pi r^2KC, and the resistor''s role seems to only affect the time it takes to charge the ...

18.5 Capacitors and Dielectrics
The top capacitor has no dielectric between its plates. The bottom capacitor has a dielectric between its plates. Because some electric-field lines terminate and start on polarization charges in the dielectric, the electric field is less strong in the capacitor. Thus, for the same charge, a capacitor stores less energy when it contains a ...

Untold secrets of the slowly charging capacitor
For points between the capacitor plates, the magnetic field due to the surface currents mostly cancels the magnetic field from the near-infinite length charging wire, resulting in the well-known reduced field in that interior region.

The switch is closed, and charge flows out of the capacitor and hence a current flows through the inductor. Thus while the electric field in the capacitor diminishes, the magnetic field in the inductor grows, and a back electromotive force (EMF) is induced in the inductor. Let (Q) be the charge in the capacitor at some time.
