Magnetic field of a bifilar pancake coil

[ET-Power]

Great progress guys, when you get a break look at these.

Super cool, thanks for sharing!

[ET-Power]

Finished building coils. I also made a single wire pancake, to be connected to the pulse genereator. It didnt make sense to use the bifilar coil with the pulse generator. The impedance is much to low to have a proper power transfer, so I will use a standard pancake coil, which has a higher impedance.
Its the dark one in the middle.
I already had one, so now I've got 5 bifilar coils, and 2 single wire bifilar coils (to connect in series with the IGBT pulse generator)

Beautiful!

I think as long as the receiver coil gives the forced cancellation
war a venting location then it takes the path of least resistance.

Just speculation.

And on another note "YES" it is from a quote

The spirit of the man IS the candle of the LORD, searching the
inward parts.

In another people can search out the deep things of existence
as we have all been wonderfully made. Able to ascend into
high things and come back with the answer.

Nothing is beyond man. BTW "The SELF EXISTENT ONE" is the
source

thanks for sharing. It looks alot like i have in my mind. except for the G generator.
I want to bring them into resonance via loose coupling. not directly connected to the pulse generator.

I connected the two single wire pancake coil in series, to my IGBT pulse driver.
The IGBT became extremely hot(much hotter than with a bifilarcoil).
I guess this is because of the back emf produced, by the pulsed coils.
To avoid it, i should use a diode and a resistor in parallel with the coil, to burn the energy of the back emf.

So, I guess I will be making another bifilar pancake coil...

isnt it funny, that the bifilar coil doesnt produce this troublesome back emf?

But telsa in his patent states, the back emf of a normal single wire coil, can be fixed with capacitance... but how? should I use a cpacitor instead of a diode in parallel? I dont get it. Or maybe a fast diode and a capacitor?

I must say... these bifilar coils have their advantage (the IGBT stays cool)

[evostars]

finished winding my 6th bifilar pancake coil. best one i made so far.

the 2 single wire pancake coils could be used as a bifilar coil when series connected. perfect for a output power coil

now the bifilar pancake coils will need to be tuned with parallel caps, so they all resonate at the same frequency. its just like making music.

[evostars]

I just tested my 3 new bifilar pancake coils. They have bigger capacitance (measured between the 2 windings when not connected). and as predicted, the resonant frequency is lower, than my other 3 coils (with lower capacitance, and higher resonant frequency).

And how lucky I am, the 3 coils dont have to be tuned. the top and bottom coil are a perfect match.

@evostars,

Stating that the bifilar produces no BEMF on the Overunity site would get you covered in a truck load of rotten fruit skins; Mostly from people who can't even perform a basic reluctance equation.

[evostars]

Math on mutual inductance of bifilar coils. here we see other
concerns not just self inductance but mutual something that
must be addressed in a bifilar.

Thansk for sharing. But its again all about inductance, not a word about capacitance. And those formulas break my head. I'm skipping this one.

MAybe, I should post it, see what happens

F.Y.I

Wilcke discovered and Volta perfected the "Electrophorus" about 1775 and described the device as "Elettro Perpetua" since, after a single initial excitation (charge), under ideal conditions (low humidity and leakage), the device gave off large spark discharges continually without further recharge - the effect was perpetual.

"If the shield is placed in communication with the prime conductor of an electrostatic machine (fig. 1), with the plate grounded, the capacitor formed by the shield and the plate, with the resin as dielectric, is strongly charged. If then the shield is touched, with the plate being touched at the same time (or if the plate and the operator are grounded), the capacitor is discharged by a strong spark, but a certain amount of charge, that moved to the surface of the resin, is not removed. By rising the shield it's noted that it is now charged with a polarity opposite to the polarity at the resin surface, also contrary to the polarity of the electrostatic machine used to charge the device. A similar effect can be obtained by charging the resin B by frictioning it with a dry hand, with a flanel, etc. (fig.5), placing then the shield over it and touching the shield and the plate, which is the most usual form of charging the electrophorus. The resin can continue with an useful charge for hours, even for several days, if the humidity of the air is low. It's interesting to note that the charging method using an electrostatic machine, although clearly mentioned by Volta (and that works very well, see the video below), is practically not mentioned in the posterior literature about the electrophorus." is a quote from this site:

Electrophorus

The point - many, if not all, the questions have already been answered in one way or another under various disiplines and topics; however, like in Volta's Electrophorus, some of the various characteristics are quite simply "practically not mentioned in the posterior literature."

Also, a focus on fueless generators or BTG has not been a topic of any real technical interest. We are generally educated to believe it is impossible so we do not seek it, and if we happen to encounter BTG by eureka, or whatever, it is dismissed as an anomaly or error, thus it is "practically not mentioned in the posterior literature."

As well; many of the "requirements" for achieving BTG are in fact counter or opposite to what is sought during conventional design engineering. For example, a super regenerative receiver is quenched long before BTG is reached since the objective is amplification of an external signal, not a fueless generator. A Traveling Wave Tube (TWT) Amplifier or Magnetron's design goal is not BTG.

The point - consider at least some of the existing relevant theory and science but do it from a 'different' prospective or point of view and extend the "practically not mentioned!"

Another Point possibly worth mentioning - pay particular attention to the "double integrals" often found in conventional equations!

Nice colour BroMikey

your quote:
"Some I know in this field have stated that their forms of conflicting
intentional waveform cancellation devices caused heating, power
wasting until such time as the node or specific res or whatever we
want to hang on it was reached. At this point a a slight to moderate
dip in working current was noted while energy began funneling into the
project without explanation."

Milehigh quote.

Quote from Milehigh,

"Therefore my questions still stand".

"What is the Tesla series bifilar pancake coil good for? What can you do with it"?

This is coming from a guy who puzzled over a question from me as synchro1 about inductance that any "High School Sophomore" could answer with little difficulty.
