Magnetic field of a bifilar pancake coil

[evostars]

The circuit works!
325V peak to peak resonant sine @ 81 KHz
from simulated back emf.

Jee you work fast, you can officially color me as blown away, I deleted that post as I thought it might a distraction. I think that video is really cool. Im looking forward to study that. What got me interested, was when i approached and retracted a magnet to a flat bifilar series coil, attached to a multimeter I got the most powerful reaction I ever seen ( except for one other geometry).

Thanks! It was pretty related I think. On topic.

Yes the bifilar coil has some pretty cool Magic!

the circuit works, and the attached photo shows the pulse that triggers the resonant sine wave. But I have found out by experimenting with this circuit, the maximum voltage of the resonant sine wave is achieved when it is pulsed at its maximum, that is 90 degrees of the phase.

This confirms my theory:
when a voltage is applied to the bifilar tesla coil (patent 512340) the dielectric field will be instantly at full capacity.
A capacitor has a charge time (as the plates are not directly connected).
the "plates" of the bifilar coil are connected, so the voltage difference is instant, and therefor the dielectric field is instant. there is NO charge time. the energy is instantly there. how much energy is dependent on the capacitance of the coil.
more capacity also lowers the resonant frequency.


This is very important. because this makes 2 kinds of resonance possible.
magnetic resonance induced by magnetic flux.(square wave)
dielectric resonance induced by dielectric flux (instant voltage, like a back emf spike).

these 2 resonances can be combined and added up. which increases the voltage of the resonant sine.

if a square wave is used to pulse a high inductance coil, a parallel coil will be brought into magnetic resonance.

the square wave creates a back emf, this is stored into a capacitor.
the capacitor is discharged into the resonant coil, as a simulated back emf spike. short and intense.

this creates a dielectric resonance on top of the magnetic resonance.
doubling the voltage/energy in the resonant coil.
In fact we use the energy of the pulsed coil twice!

a third coil parallel to the resonamt coil, will resonate with the middle resonant coil. this coil can be used as an output. rectified and stored as DC in a capacitor bank, that feeds a load.

Hello evostars !


very nice work , this is similar to the behavior of Extended Tesla bifilar coil ( ETBC ), we are using different technique but we arrive to the same point

thanks! I looked into the extended coil earlier, and made one from kitchen aluminum foil, and flower wrapping plastic. Very labor intensive.
have you found a way to produce a coil with larger capacitance (plates) that is easier? Where can I find you research? I believe I already read a document of yours about the etbc

Larger capacitor isn't easy to produce, the max value i got is 90 NF even you can increase it using etching technique the same as they produce electrolyte capacitor , i tried this technique and i had X10 time more capacitor , in my thread you can see all my research , i only have one PDF :

www.free-energy-info.com/Mohamed.pdf


part 2 i produced the correct model with some geometrical transformation but i still need another step ( will be explained very soon )



the idea is to build a compacted Tesla wireless system able to work as transmitter/receiver the two at the same time , in the other hand you can replicate power with radio frequency speed bypassing lenz effect .

Thanks med3012
I remember your pdf, I looked at it last year.
A multilayer bifilar coil, could also have increase capacitance. (if you use speaker wire, so the coils are stacked).

if you have 4 unifilar pancake coils, stacked.
top coil being nr 1; bottom coil is nr 4;
connect 2 to 4 to 1 to 3. (series like tesla patent 512340)
2 is plus, 3 is minus. this way inductance is increased, and capacitance is increased. there is a large voltage difference between coil 2 and 3.
and the inductance is also increased due to coupling.

two series connected inter-weaved bifilar coils, AKA
QUADFILAR

small update

after I found out the capacitor discharge to make a bifilar coil resonant needs to be at 90 degrees of the sine, I have worked out a circuit, based on the very fast hef4528B.
This should make it possible to switch very fast, so the ring toroid isnt needed any more.
design/build is in process

circuit error, new design with pulse transformer

Thanks med3012

The circuit works.
A nano pulse (0.09mJ) from a capacitor creates resonance in a bifilar coil(0.53mJ).

But I designed it in a way it doesn't work properly.
Its a good lesson. and I will correct it.

I had a resonant coil grounded on a charged capacitor, and I connected the open (resonant) end of the coil to ground.
This way it discharged the capacitor through the coil.

But (expected) the resonant sine, also was grounded, and therefor interupted, when pulsed at maximum voltage rise.

I learned a lot about switching mosfets, I will now redesign using a pulse transformer. So the source doesnt need to be grounded, it can connect to the capacitor.

The resonant coil will be grounded, the open resonant end will be connected to the drain of a mosfet (with an extra diode).

The back emf charged capacitor will be connected to the source.
A pulse transformer secondary connects the source to the gate. The primary will be pulsed very shortly, so the mosfet opens and closes fast. (that is the goal at least).

I'm still not sure about the phase angle of the pulse, but power is voltage times current, so I'll try to nanopulse at 0V (0 degrees) of the resonant sine, when the magnetic field is maximum.

The other option, is to nanopulse at maximum voltage (minimum magnetic field), at 90 degrees. This will increase the dielectric field energy in the resonant coil.
If I'm lucky, this could make the dielectric and magnetic field in phase, resulting in power.

Theories will only be supported by the truth of the experiment.

@evostars,

Skycollection's stacked bifilar's are not connected and pass power through inductance. Skycollection measured the output of a Hexafilar through a resistor under guidance from Conradelectro.

The results showed that voltage drops across the load coils from top to bottom while amperage remains unchanged. This is the opposite from an electrical connection where voltage remains constant and amperage drops across the load.

The practical advantage to this kind of transmission system is that the power plant can instantly tailor output to the load across the grid simple by increasing the voltage instead of generating amperage. The grid can't generate amperage instantly so it needs to run it's generators at maximum output all the time. This results in pumping water uphill with the excess power to store it and have the potential to divert to the grid when it's needed.

Tesla generated power by coal furnace at "Wardencliff", to charge a large bank of storage batteries. When power was drawn by a receiver station, Tesla could instantly transform his stored D.C. power to higher voltage to match the load. The inductance transfer of power relationship between the broadcast antenna and reciever in Tesla's wireless system is identical to the bifilar coil's stacked in close adjacency; The power transfer is still wireless! The measured voltage along the "Inductance Grid" remains constant. The voltage increases only to match the load, while the mainline voltage always remains unchanged.

When Coradelectro asked me for a test on my multifilar coil, I did not give him the correct information, I gave him other information to see his reaction, as expected, he decried me with astuteness but the real results are going to be known very soon with a very qualified businessman and expert in electronics in United States.

You gave false information?
To see his reaction?

I dont understand why you would do this?

Nelson Rocha has already hit a hard wall, trying to do business.
Secrets can make you an easy target, NDA's also!

I hope you will share your results and insights with the world skycollection.

Is there a reason why you dont have 4 multimeters, so you can show DC voltage and current on the input and output side of your very inspiring video's?

[mikrovolt]

I may be overly precise about self resonance I tend to ring a coil like a musical instrument however the bifilar pancake coil construction is not like a tuning fork. It's current configuration tends to absorb. I think that the bifilar pancake should be solidly fixed to a solid sheet to be a true resonator. This is why I think Conrad's idea is good but something is still lacking where I would say completely 100% happy with his resonance. UFO should feel good about his own work and configuration has credit.
There has to be something to this music thing, sorry for any trouble I caused.

welcome evostars !


for sure experiment is the only way to go , sometimes the theory can enhance or correct the experiment .. the final goal is to have something that work !
