Sharing ideas on how to make a more efficent motor using Flyback (MODERATED)

Do you think this would happen with a diode is between the two coils so only the flyback (collapsing field) can go through?

First draw a schematic depicting these two coils, power supply, diode and the switch.

Here at the first page of this topic was a post with video demo done by woopy exactly following my instructions. You will see a schematic in his video and the device operating. Please note that later on woopy confirmed a 0.3uf capacitor give best rpm results. I have also suggested the ideal capacitor value to be chosen with the motor under load as more torque may be favorable over rpm which would require a little more cap uf value.

Then, yes - the reed switch will fail pretty quickly if the 1μF capacitor is deleted and most of the energy will be radiated away in the resulting arcs.
That capacitor has almost 0Ω impedance when the switch opens, while the second (high inductance assistance coil) has ∞ impedance when the switch opens.  So this capacitor makes a world of difference.  That's why the system slows down when the capacitor is disconnected.

Of course after the time equal to π(LC)^½ the capacitor will spontaneously charge the 2^nd coil and after another period π(LC)^½ that coil will recharge the capacitor back (albeit with an opposite voltage polarity), and so on ...over and over - in the typical sinusoidal self-oscillation manner of an LC circuit. 
If the rotor magnets approach and depart that "assistance coil" at the same frequency as the natural self-oscillating frequency of the LC circuit (119Hz for Woopy), then a second resonance (mechanical-LC) will appear and the entire efficiency of the motor will increase even further.

It would be better to move the 2^nd coil behind a 2^nd switch and energize it from the charged capacitor at a proper time and with greater timing control. 
The voltage to which the capacitor becomes charged to (before the 2^nd switch closes) will be a measure of the recovered energy according to the formula E=½CV²   
The largest energy loss in this circuit is caused by the diode voltage drop (~0.6V) and that's why a synchronous MOSFET rectifier would increase the Inductor --> Capacitor energy transfer efficiency, even further.

About two weeks ago I spent a couple of days explaining more or less the same stuff about inductors and capacitors and I gave a half a dozen coil-flywheel explanations in great detail and at the expenditure of a lot of effort.

I clearly got almost nowhere with that thankless endeavour and I am almost certain that I will never make the considerable effort and invest the time to do it again.

I noticed and there will always be some individuals that this is wasted on.  I just treat it as community service.
There seems to be this intuitive conviction that the same type of components are the best energy receivers for each other, despite that life is full of examples demonstrating that opposites complement each other the best....like hand in glove.

BTW:  I monkeyed off the flywheel examples from you.  Grumage could probably even make instructional videos out of them if he did not have to pay for materials.
