In this experiment i am using a bifilar pancake coil....is this like you say...?

Hi Skycollection,
No, I dont think so. But that video of yours is interesting.
It shows the rotor, at the side of the coil (the middle) is the right spot.

For me, I'm not working with moving parts. only moving fields, created by resonance.
One resonance created by the start of the current (instant voltage change of a pulse).
And another form of resonance created by the interuption of the current (back emf).
This resonance shows no magnetic field properties.
But both resonance have one common field, the dielectric field, observed as a sine wave voltage.
If these 2 sine waves, are in phase, the voltages add up.
Not only that, the magnetic field and 3rd field also inter act.

Normally back emf is burned away, but this time, this massive instant voltage energy is re-used, by storing it in a capacitor, that is part of the already (magnetic) resonant coil.
All the fields combine. Its like a little trick in time.
Its still a work in progress.

PM me if you want a quicker reply, I dont hang out on the forums.

I made a video explaining how to easily make a bifilar coil from speaker wire, and how the fields are situated:

You can stack multiple coils in parallel to increase capacitance.

update:
I have designed a circuit in LTspice, that is supposed to do what I want.
I'm now designing the board. Very exited about this.
If it works, I will share more, but it might need some tweaking.
(Bifilar pancake coil Resonance, without a magnetic field).

Circuit board is ready for testing and tweaking.

the circuit works.
It showed me you can bring a bifilar coil into resonance by injecting it with high voltage.
the high voltage injection should be like a simulated back emf spike. High voltage, but ultra short duration.
The voltage can be captured from the back EMF of a pulsed coil.
Stored in a capacitor.

This capacitor is than discharged via the resonant coil. giving it a pulse.
Just like ringing a chuch bell/clock with a hammer. A high energetic short duration pulse, making it resonant.

The timing of the pulse should be at the top of the resonant sine wave when the back emf voltage is positive.
In relation to the 50% duty cycle pulse to create the positive  Back EMF, it should be at 25% (90 degrees).

So in conclusion:
There are 2 ways to bring a coil into resonance.
1 is via magnetic flux (parallel coil with 50% duty cycle)
the other way is via dielectric flux. (directly into the resonant coil).

So, when a coil A is pulsed with 50% duty cycle @ resonant frequency of parallel coil B,
positive back emf of coil A is temporarily stored into a capacitor.
Coil B is resonant from magnetic flux of coil A producing a resonant sine

at 25% duty cycle (90 degrees resonant sine, at Vmax) the capacitor is very shortly discharged (like a back emf spike simulation) into the resonant coil.
This energetic spike, also brings the coil into resonance. producing a sine.

As the coil already was resonant from coil A's magnetic flus, and the resonance from both methods are in phase, the coil will add up the voltages of the sine wave. Resulting in a stronger field. both magnetic as dielectric, as they transform into eachother when resonant.

One nice observation: a 25V capacitor discharge produced a 325V resonant sine (peak to peak).
The capacitor doesnt discharge completely.
The capacitor can easily charge up to 200Vdc...

The geometry of the electric field is expanding (or contracting) radially.
The perpendicular magnetic flux in the vertical domain is also expanding
or contracting, radially.
This creates a secondary electric flux, which is in the vertical domain.
and it, a secondary magnetic flux in the horizontal domain.


At resonant frequency, the two magnetic fields cancel out. They are
exactly equal and opposite. (in reality the 2nd field is slightly smaller)
However, there is not complete cancellation of the electric flux.
There is still an electric flux at the point when V should drop to 0.
This induces an opposing magnetic field of 1/4 period, occurring twice per
oscillation.


This is the magnetic moment caused by capacitive inductance.
there is no opposing force to this induction.
And has a frequency-doubling effect.
It's amplitude is less than that of the initial signal.
But drawing from this current has no effect on the induction of the
primary impulse, because the initial signal has no flux at this time.


Electric flux is completely outside the coil.
