There is current flow within the TBP that is recirculating and creating induction in the windings, but little current exits the circuit at the frequency shown in the example.  This circulating current is the result of energy transfer between the winding inductances and the distributed capacitance between windings. 

that could explain the absence of the magnetic field in Nelson Rochaa's video:

Very interesting. this is tickling my brain in a pleasant way. 
I wonder what this frequency is, and if I can find it with real coils.

Thanks Partzman

Tesla states that the series bifilar pancake coil generates 250,000 times the electrical potential as the single wire coil of equal turns. He goes on to state that it's the elevated charge storage that cancels the self inductance at any input current or frequency; Hence, as evostars points out, the bifilar "Never Generates Any Flyback"!

The biflar coil generates a stronger magnetic field than the single wire coil when it's pulsed, as I've been pointing out for over eight years.

Pulsing the iron nail core through the single wire coil, first produces a "Positive" current, then when the current's interrupted, a "Negative Current" pulse follows. This cancels the "Impulse Magnetization" effect.

The series bifilar doesn't generate a negative "Cancellation Pulse".

"Tesla states that the series bifilar pancake coil generates 250,000 times the electrical potential as the single wire coil of equal turns."

Well he describes that number with a coil of 1000 turns with 100v in and .1v between adjacent turns. When we jump to say 100 turns, then there is 1v between adjacent turns which shifts that large bifi number to 25,000 times. So if it were a 10,000 turn coil, the effect is 2.5mil times. Perspective...

With a normal coil the more turns, the worse the capacitance gets. More turns, more division of input V between turns. The closest a bifi and single wire coil get is in 2 full turns. As the no. of turns increases for each, the capacity goes in opposite directions for each while the inductance and resistance remain the same for each. All if each coil is identical in wire and turns and geometry of the windings,

ok.  Dont know if you have a duplicate of a bifi in single wire with same ga wire and no. of turns to compare the bifi upper resonance to. Id be interested in the effects possibly with inducing the single wire from the bifi if they were in res at the same freq. Im not asking you to do it, but its part of what I want to do.

And.... 

"I'm not sure if this will address some of your other points including the single wire, but say we take one winding of the TBP and drive it with a sine generator while leaving the other end open, then use the other winding as a secondary with a load.  We are now creating induction in the secondary with the displacement current in the distributed capacitance between the windings.  Is Lenz still in effect?  What will our overall Pout/Pin look like?  Lots of room for experimentation here!  Perhaps there is a use for the TBP"

That is on my list i posted day one of me posting here.  Have you done this?

Mags

Mags,

Yes, not with the TBP specifically but with stacked pancake coils.  The schematic below shows the actual circuit used to produce the attached scope waveforms which are part of my MEI or Magneto Electric Induction research.  The basic device consists of pcbs with foil traces on both sides stacked with a dielectric material in between creating a special transformer with transmission line characteristics.  This transformer primary has one end open with the driven end appearing as capacitive reactive load to any generator source.  Therefore, a square wave generator drives the primary thru an inductor which resonates with the input capacitance of the primary and producing induction in the secondaries thru displacement current as previously mentioned.

The scope pix shows the various waveforms of the probes in the schematic with the resulting input power in the Math(red) channel  equaling -1.7 watts rms.  Also note the phase between the input current generating the voltage across the 1 ohm sense resistor leads the input voltage by 90.42 degrees.  The output voltage on CH3 is 8.07v rms which produces an output power thru the 51 ohm load of 1.28w rms.

The caveat to all this is that the infinite power gain is referenced to the resonant input sine wave driving the transformer with no consideration of the power consumed from the square wave generating source.

Research into this type of generator is ongoing.

Do you see any core?  Where do you suppose the energy
(or whatever you would like to refer to it as) is being stored?
snip...

The energy is stored in both the magnetic field produced by the current through the coil and the distributed capacitance of the coil. No core required.
BTW - it was Tesla, in his own words, who referred to energy being stored.

Read Tesla's patent again.

https://teslauniverse.com/nikola-tesla/patents/us-patent-512340-coil-electro-magnets

He doesn't say that the electrical potential generated is 250,000 times greater in the BFC, he says the energy stored is 250,000 times greater than that stored in a SWC, (assuming a 50V potential between adjacent windings in the BFC). Big difference.
