Hi Mick,
As the capacitor is the exact opposite of an inductor the part which is the flyback voltage in the inductor can be considered as current in the capacitor. The capacitor gives back a current kick where the inductor gives a voltage kick. The kick back form an inductor happens when opening the circuit as the energy is stored as a magnetic field which is charges on the move. This induces a voltage when opening the circuit as the inductor works like a constant current generator in just that instant. I.e. the current can't just stop immediately by opening the circuit as the current is continuous meaning its value can't just make a jump. Consider this like inertia in a mechanical device or energy preservation. The capacitor has the tension (voltage) continuous and thus has to make the jump in current instead. This happens when the circuit is closed which is exactly opposite to the inductor.
Connecting a capacitor and a n inductor in a closed circuit while energy is stored in at least one of them will make them oscillate forever if there is no resistance involved. This is only achieved with ideal components as real components have resistance because of the metal conductors they are made of. The oscillating frequency is the resonant frequency of the circuit given by their capacitance and inductance values.
The conclusion is that the magnetic field is stored when the current is running (closed circuit) and the electric field is stored when no current is flowing (open circuit).

Treat this like a micro strip transmission line of variable width. Ivor Catt treats capacitors as transmission lines and has the same point of view as Wilbert B. Smith that the charges can't be stopped. Smith thinks that the electrons die (dissolves) if stopping them as a smoke ring will die if stopped moving. By treating capacitors like transmission lines there is no need for Maxwell's displacement current. The charges just have to always be on the move. When charges are moving they create the motional electric field (William J. Hooper) that can't be shielded and act like gravity and perhaps are exactly the same thing. Or gravity is the induced motional electric field. Read Smith and Hooper for the theory or study the theory of rhythmodynamics. Moving charges also induces magnetism thus the electric part can't really be separated from the magnetic part as well as the moving part. All three components make up electromagnetism and the parts can't be separated but the magnetic fields can cancel as well as the motional parts. For canceling the electric field positive charge carriers (positrons) would be needed. But when meeting electrons the positrons and electrons will annihilate each other. Using the smoke ring analogy the smoke rings will break up when meeting as their spins annihilate each other. Two smoke rings of the same type can combine. I.e. electrons or positrons combining to other elementary particles like three electrons becoming a quark.
For more on the fundamental forces see the Rhythmodynamics theory. All is waves. Even what we perceive as particles can be described as waves according to that theory.

Ole,
What dynamic of a capacitor if any could be considered analogous to a
flyback pulse in a coil?
Being a capacitor stores rather than moves charge perhaps there is no
analogy.

Could be what induces the force of gravity the stress between plates
(planets/stars) creating a torsional stress never to equalize charge as
long as energy is being sourced from a star.
Back to Norm's what is heat, if the star is sourcing positive ions as it
is radiating heat...
