Tonight I explained something, and it reminded me of the hall effect
(https://nl.wikipedia.org/wiki/Hall-effect#/media/File:Hall_effect.png)

Why does a bifilar coil when pulsed with ac regular show a magnetic field, in the same direction, at different frequencies?

On what physics, is tesla's claim in his patent 512340 :
I have found that in every coil there exists a certain relation between its self-induction and capacity that permits a current of given frequency and potential to pass through it with no other opposition than that of ohmic resistance, or, in other words, as though it possessed no self-induction

I think it has to do with how the fields act.

normally(single wire coil)  the magnetic field wraps against the magnetic field of the next winding, counteracting it. bad thing. The voltage differnce between the windings is minimal, so the dielectric field is weak, giving a very high resonant frequency.

but with the bifilar coil, due to the much greater voltage difference between the windings, the dielectric field is much stronger between the windings. when it is strong enough (voltage dependent i think) the magnetic field is blocked, it cant flow in between the windings(only in 1 direction, but not the opposite) , because the dielectric field is there. It blocks the magnetic field. ( Hall effect, but aplied to the weaker magnetic field due to the stronger dielectric field)

the magnetic field will keep flowing over the windings, and over the dielectric fields (at 90 degrees of the dielectric field)

Sorry  hit the post by accident if you see this before i edited it. now...

Id like to think that there is a different activity happening in the bifi, and I think it could be something we hopefully figure out.

Nice idea on the possibilities.  Sorta the same as I described as the possibility that at resonance the 2 coils may be ignoring each others inductance thus the possibility that the working inductance is only the value of each windings inductance.  Im saying possibly as some will say its not and we need to prove what we think or its just same ole same ole. ;)

I found out that by pulsing a bifilar coil with back emf, I can make it resonate with a third field, that doesnt have magnetic properties.

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:
https://youtu.be/ZKP9Bgpqa5E

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).

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.

At resonant frequency, the two magnetic fields cancel out.
No they don't. This is a common misconception.

The coils in Tesla patent 512340 do NOT cancel the magnetic field.
The windings are wound in the same direction.
the magnetic field polarities of both windings are the same.

Since the capacitance is increased, there can be more energy stored in the dielectric field,
resulting into a stronger magnetic field at resonance,
 when these 2 fields transform back and forth into each other.

I tried to prove there is a third field. By showing resonance without a magnetic field component.
This is not true. Resonance, is still between electric and magnetic fields.

The "apparent" non magnetic field I tried to prove, actually was a magnetic field that was more north than south(or vice versa), due to the long duration (50%) positive pulses I used to get the coil into resonance.
 
This resulted in a swing of the compass, as the resultant vector of the fast changing magnetic field wasn't zero.

But It can be zero!
 the magnetic field can be perfectly balanced, resulting in dielectric/magnetic resonance, that doesn't swing the compass needle.

The way to do this, is by instant voltage. off-on-off.
A simulation of a back emf spike, that has high voltage (energy),  but is instant.
It  has no duration in time. To do this is to connect and disconnect (instant) a charged capacitor to the resonant coil.

 the resonance produced by this method is rather special. it has a much higher voltage then the original spike.
This is because, the counterspacial dielectric field bewteen the windings is instantly there. as soon as the voltage is applied from the cap, the voltage difference is instantly there bewteen the windings. it takes NO TIME, the dielectric field is instantly there.

In comparing with a capacitor, that needs charge time, because the plates are not connected,
the bifilar coil needs no charge time, the dielectric field is instantly there!!!

Now think what this does at resonance... where the fields transform back and forth between dielectric and magnetic.

The Sine wave representative of the dielectric field strength (voltage) reseaches its maximum voltage, and is charged instantly by the capacitor to a higher voltage. charge is even a wrong word... as it indicates time. it is instant.

this higher voltage, dielectric field, @ resonance transforms into a magnetic field, and back into a dielectric field (negative) and back into a magnetic field (negative) and again back to a positive dielectric field, where the whole process starts again.
But this time the dielectric field is stronger (only a small loss from wire resistance), than before. Again it is pulsed. the voltage becomes higher and higher...

super empose this onto the magnetic resonant sine, and we've got a runaway.
more and more voltage, stronger and stornger magnetic fields.
only restricted by the wire resistance, and the switching mechanism.

To create a output, simply ad another resonant coil in parallel, tune it to the first resonant coil, and rectify into a capacitor bank, to feed a DC load. the load, keeps the voltage rise under control. clipping of the top and bottom of the sine wave making it more like a rectangle...

This is what I'm working on, and what I'll keep doing until it works.
I'll use my youtube channel to explain it in smaller steps.
this is the playslist so far:

In C.P. Steinmetz his book
"Elementary lectures on electric discharges, waves and impulses, and other transients" from 1911,
he describes how electricity works, in a way that is very logical, by using the dielectric and magnetic fields.

It has inspired me greatly.  I'm very grateful Nelson Rocha shared his first edition of this book with me.  ;D
 It has given me great insights in how a bifilar coil really works, and what we can do with it.

I am making a video series explaining the fundamentals, and how this is translated to the bifilar tesla pancake coil.
These are the first 3 in the series (more to follow, please subscribe on my youtube channel)

Lesson 01: Fields; electric energy stored in the dielectric and magnetic field
https://youtu.be/NSKKbEo6fzI

Lesson 02: Power, inductance and capacity; and how they relate.
https://youtu.be/LclozdKdZRc

Lesson 03: Infinite voltage and current; and how the time factor plays a role
https://youtu.be/zmZxQp1PW1U

I hope this will inspire more people.
Together these 3 videos hold a lot of information that when combined are priceless.
