Suppose we have an Ideal $LC$ circuit with an open switch at time $t=0$ where the capacitor is initial charged to a voltage $V$. The instant the switch is closed, the typical $LC$ oscillations will begin. But what electric field actually causes these oscillations to begin? At time $t=0+dt$ the electric field in the circuit should appear as follows:
Note that there is no electric field inside the superconducting wires and similarly no field in the superconducting inductor. If this is the case, where is the electric field that supplies the initial force to get the electrons in motion? We know that $F=ma$ and electrons have a nonzero mass so they can only gain speed (they are initially at rest at $t=0$) if there is a non-zero electric field at their position. So where is the electric field that supplies this force?
My second issue is that there does not appear to be any location where an electric field can exist to supply the back emf. It is this back emf which must be overcome in order for the creation of a magnetic field within any inductor. That is, when we wish to create an magnetic field, we must do work against an electric field that opposes the motion of the charge and that energy supplied in opposition to the back emf materializes as energy within the magnetic field that we create. But there does not appear to be any field that could possibly provide that resistive back emf to oppose the motion of the charge of the current. Think about it this way: Imagine a positive charge moving from the positive plate to the negative plate as the capacitor discharges. In its traversal of the circuit, not once does it encounter an electric field to take away the energy it possesses and transform that energy into magnetic field energy? So then where is the location of the electric field providing the back emf?
Any help on this issue would be greatly appreciated as this issue has been driving me crazy!
