I have always wanted to understand it but no one has explained it like you do thanks so so much
Thanks!
I love the way you explain things Master Ivo, you always start from the basic principle and it's very important not to miss any information in passing, to understand the two-wire coil before you tackle the electrical circuits and how to use it. :)
You are the best I thank you for all the quality of your work and all the personal time you invest for those who want to discover this unique type of energy.
thanks Bruno. much appreciated. indeed step by step explaining all the details, for replication
If I may inject a slightly different understanding of my friend Nicola Tesla. In his explanation of the actions of electrons and coils, he sometimes often uses the term capacity and capacitance interchangeable with more general terms we call amperage and voltage impresses, and not distinctly with the modern term of capacitance as in a device we call a capacitor. Often here his meaning in general understanding is simply the activity of the coil has the capacity to increase the flux potential of power, i.e., voltage and or amperage.
3D visualization!! Amazing addition Master Ivo 🙏
Thanks, I love that VR is able to show this
This was brilliant! Very well explained. I feel like I understand how the coils work now!
In my Tesla research, I discovered that Tesla purposely left key elements out of his patents after realizing they could be used against Humanity.
for example P?
@@gabrielferrara9111 Coil winding techniques is one. Niko could visualize his inventions in his mind and see how they operated if a certain change or proposed improvement was made. Also, after having so many of his patents literally stolen by unscrupulous 'inventors' like Marconi (who was later found in court to be a patent thief), Niko saw that he would have to keep certain subtleties out of his patents in his head only. This vid of mine tells more: ua-cam.com/video/6EZmGSnDcU4/v-deo.html
Of course
I keep adding things to his works

Excellent video. Love your insight and the VR presentation. Thanks for sharing!
Thanks!
Excellent work. This is the first lecture I have experienced using VR. Thank you!
Thanks, I've been wanting to show this, but never was satisfied with 2D drawings. Fields need to be seen in 3D. Even Steinmetz drawings don't give the fields full credit.
Interesting. I read a few times this patent, however, the fact that you have put coils side by side, it's really easy to see the capacitor. Thanks for that!
2 bifilar pancake coils, with one positive dc offset, and one negative dc offset, will also create a dielectric field between them (like a capacitor).
@@MasterIvo I agree. ;)
If those coils then are impulsed, the dielectric field between the coils is?
@@MasterIvo You tell me! I don't know where you are heading with your question or the purpose?
@@donaldwright2426 the dielectric field is reduced in voltage very fast. this represents current. but a longitudinal current. Magneto dielectric (ringvortex)
Nice vid! Covered a lot of field theory there, was great to see. Looking fwd to next instalment!
Wow! You explained it all very nicely. Great video.
thanks
9:34: Hooking up the red to blue and blue to red is like an electrical Mobius strip! Wow!
Thanks Master Ivo. Please go ahead... nice VR visualization. Waiting for the next class. May God bless you!
thanks, next video will soon be released.
Awesome information you have given us. You are very appreciated. Thank you!
Thanks Steve, you are also very appreciated, thanks for all your efforts.
I really appreciate your lecture, l went through school in 1970. After my degree, I taught in a local college. I have forgotten most of my education in electronics. I'm still interested in learning more, [ha ha] is good for me.
Thank you!
Thanks brother, you make it easy to share with those whom cannot visualize. This would be a great teaching aid. Look forward to you next video. Peace and Cheers!
Thank you Claudio. VR is a very strong tool for lectures. I wish in the future VR will be more wide used, so I could give a live lecture in VR, and everybody could join in VR (this is already a possibility now!).
@@MasterIvo you are right brother!
Wow I appreciate your newest video display skills. Great job sir.
Nice explanation Ivo :) I like the way this is going.
Thanks dkdyker :)
Amazing. You continue to blow my mind
Another term used to express what occurs within a bifilar winding coil is “constant shear force”. The electrical shear force is constant all the way around. I have tested bifilar winding coils versus conventional winding coils, as near field antennas. The difference is stunning. Bifilar is about 10x more effective than conventional.
Merci pour l'information
i love you man watched one video and subscribed, you explain break it down then expand. wish some of my school teachers would take the time. cheers!
Thanks Joey. there is still a lifetime to learn and explore.
Congratulations this is top notch stuff.
Thank You Master Ivo your teaching method is excellent you made me understand the bifilar coil I get it
Thanks Master Ivo, it's the perfect class room! Thanks Tesla too!👏🏻👏🏻👏🏻👏🏻
Thanks :)
You are amazing. I'm a new fan. I'm bog on Voltage and Dielectric Fields.
Love the CG on what looks like Oculus?!? Great video as always and very glad you are educating people about these things
Thanks! yes, Oculus quest VR, with google Tilt Brush
Great insight. what's the resonance frequency if that sorta LC created by the bifilar pancake coil?
Excellent explanation!
By connecting the two coils he is basically making a magnet because the fields now end up being opposed in direction to one another, and not as you have described as ending up in the same direction. At the start you show the magnetic field of the single coil as being opposed to itself in direction on each side, but it should be in shown in the same direction (as steinmetz says, these are connected in reality so they are in the same direction). This is quite important because with the adition of the second coil (and shunting the wires) Tesla is essentially making a magnet out of the bifilar coil (which is now become one big wire). This means the fields are now coherent and in reverse phase to one another this is what makes the dielectric manifest stronger
This are principles of step up energy via manipulation of flow and compression of voltage through a series of more friction to produce more resistivity. The mangetic forces should fallow the ideal concept of plutonic symmetrical shapes, and shapes should be made according to the desired directions and interactions of the magnetic fields. The key is all about having the right shape and symmetry to modulate and control energy both in the form of vibration/sound and electricity/voltage. Interestingly enough, none of this science is new about fractal and plutonic shapes and assemytry is energy manipulation. Ancient texts, temples, display such knowledge of cymatics and energy manipulation through shapes and proper elements.
Thank you! that's how educational videos should be, clear explanations with drawings, just donated!
thanks Omid!
Nice work. Great VR display.
Thanks :)
yeah, he did a great job on this didn't he? very pleased to see this being used. the tools definitely could be improved as far as vr modeling options go at the moment.
Master Ivo you da man!
Good explanation of a typically hard to interpret Tesla patent. Good job. 👍🏴
thanks!
Thank you for explaining the vortex
:) more to come in the future
Thanks,nice explanation.
Really Awesome!
very well explained. thank you
Thanks!
Love the VR guide. Thanks.
What is the craziest thing you think we could do harnessing the power of the dielectric field?
Thanks. Craziest? pfew... so many possibilities. Control gravity, generate electricity, and everything that comes from that... use your imagination
@@MasterIvo Wonderful. I was hoping you would suggest gravity. Cheers Master Ivo!
@@deeznetz :D
Bifilar windings are used to minimise coil inductance. For example in wire wound resisters
yes then they are counter wound. in Tesla's coil they are not counter wound.
Inductance isnt zero actually. it does not cancel out. More on that in a future video about impulse generation coils
Very good. Thanks 😊
Thanks Metonia!
Thank you, very interesting and well explained
Thanks :)
Great video! Two questions. 1) what impact does the insulation of the wire play in terms of capacitance (and so, energy) and 2) at what point does the energy overcome the insulation of the bifilar coils? Does it lead to arcing?
the pvc acts as the dielectric material of the capacitor, it's dielectric constant will influence the capacity.
I dont know the exact dielectric breaktown voltage of pvc, but you can look it up. over the threshold it will arc over and destroy the pvc
Would a spherical coil work? Or do they have to be disc like?
6:14 there are still videos of Schawberger's vortex geometry models available on youtube.
13:52 Schawberger used 2 counter rotating copper plates to create the same effect in the middle, I think.
Excellent information.
Thanks :)
At 13:05 the capacitance of the wire itself is 679pF but earlier at 08:33 the coil was connected serially to itself thus its plates are connected I can clearly see them connected at 13:25 so the stored energy must be different.
V Good Video thanks for posting
Très belle video
je vais la visionner encore pour bien la comprendre
Merci
Hi Master Ivo, your concise videos rank at the top of most others that I have come across. Thank you very much. Please, I am still struggling with how to build a bifilar coil with two different wire gauges. Specifically, at what point during winding one gauge wire does one begin to wind the other gauge wire?
thanks.
I have never done that. But I understand you will run into challenges. It depends on what your goal is.
Equal amount of windings will give equal inductance in the 2 windings.
the big difference will be in the capacitance between the windings. As one winding will have a larger surface area the the other winding. (coax cable could als work, use its shielding, not the core).
What do you intend to use it for?
Why not make 2 bifilar coils with 2 different sets of speaker wire.
one smaller diameter wire and longer,
then the other bigger diameter wire and shorter.
with equal copper weight. (just cut 2 equal pieces of the different diameter speaker wire, and compare their copper weight, so you will use the ratio to determine the difference in length of wire.
In this video of yours, you utilized two different wire gauges: ua-cam.com/video/ZKP9Bgpqa5E/v-deo.html
I believe that various colleagues of yours have also suggested the use of two different gauges -- e.g., 20 gauge and 25 gauge wires.
Is there a "tuning" aspect to optimizing these coils based on the wavelength as well?
yes harmonic ratios are preferred
Cool video. Nice explanation.
What is the 3D program you are using?
Looks nice
Tilt brush, on the Oculus Quest
Hey Master Ivo I've been learning electronics for the past few months and you're videos are awesome for that.
I was wondering the other day, could the dielectric force actually be an absence of electromagnetic force? Like creating a vacuum or void that is no longer holding the emf back and so it rushes in.
Kind of like if you dip a dry cloth in water, the voids will become saturated through capillary action.
Or like a siphon. When the water particles move from one spot to another it creates a gap that has to be filled with something in order for it to overcome the pressures keeping it static. Its a closed system at that point within the tube and cannot pull anything from the space around the tube. So, in order for it to move it necessarily has to have something come in and fill the gap that was just left. Or vise versa, if something in the back wants to move forward then the thing in front has to get out of the way.
There are references to Walter Russell being a close and a long time friend of Nikola. After getting lost with Walter, I reread some Nikola stuff and ... wow! Much recommend looking at both: Walter AND Nikola. Super vid.
Interesting. Did he also write about displacement currents, and impulses?
@@MasterIvo
Not sure. Walter has his own terminology such as the "infinite still light," which seems to me to stand for "un-energized ether." Calling it "light" appears awkward until Walter makes his case for the optical nature of all matter. When Ed Leedskalnin steps in with his Magnetic Current booklet he *also* takes the baseline of the optical nature of matter and on top of it claims that the magnetic current consists of *concurrent* positive (N) and negative (S) magnetic streams with vortex shapes. So, it seems to me the radiation from the bi-filer coil geometry *emulates* the magnetic current of Leedskalnin in its most basic form no less.
Thanks!
Please thank you Master Ivo. Not only are you a great inspiration you are doing this open source and it’s explained very well and it’s o real. More funding will follow as I am being better funded.
What effect would this have in a generator? As in if the coils of the stator or rotor were Bifilar like this?
If I understand your explanation correctly, the dielectric energy of the bifilar coil increases with each volt we apply to it
Earlier in your video you measure the capacity of your coil at 697 Picofarads and at that moment the measurement is taken while the serial connection is open, this was in order to demonstrate that the coil is a capacitor already without even the closed serial connection.
Can't you measure the capacity of the coil if it's in serial connection?
If the dielectric energy increases to the square of the potential applied in series connection under any speculation this may be an indication why Tesla explained a way to transport energy that could be sent anywhere on earth with very little loss because the more we increase the input potential, the greater the distance to the square of it. The distance of the dielectric field is very large, much larger than that of Hertz which is limited by the distance.
So in summary if we have a quadrafilar coil of the same number of convolutions applying 100 Volt of potential as a bifilar coil with the same characteristics we will have a dielectric energy 2X greater than the bifilar coil .
If this is true to increase the energy of the dielectric field we can either increase the size of the coil by having 4 wires instead of 2 or we can simply increase its voltage at its terminals the most economical way is to increase the number of volts however both paths are possible.
Thank you Master Ivo
But increasing number of windings increases capacitance linearly (increasing "volume" for dielectric field), yet increasing voltage is exponential (increasing "pressure/density" inside dielectric field).
If you quadruple number of windings, you only quadruple capacitance, but if you quadruple voltage, capacitance increases 16x. Am I wrong?
🇧🇷 Friend, admirable your work in this video, thank you very much for your excellent explanation. 🙏🏼 Note: I remembered the Joules thief, it would be possible a video of you explaining this circuit, Joules thief and see what you could have in common with Tesla's bifilar coil.👍
joule thief works great with bifilar coil. maybe I'll show a pnp version with negative spikes
Very amusing.
I think why Tesla didnt specify usage of some of his patents is because it might be that his patents are part of his whole system. In other words its applicable to his other patents.
What people dont uderstand is that Tesla was talking about effects that come onto play on high potentials (and high frequencies). They can not use logic of low voltages. Coils can be used as resistors or capacitors in domain of AC currents. Tesla seems found a way to exclude need for external components to the circuit by this method and made it safe for use even with extremely high potentials. By distributing capacitance evenly that makes sense as use of external component could be dangerous to store all that energy into separate capacitor.
Great video.
Yes I agree Tesla used many patents as one system. he applied for the many components. One patent for the coil, one for the impulse generation, etc...
Do you have any idea at what the resonant frequency was he worked with? One question, it appears that when the center tap field collapse it will in phase with lower half of the coil and 180 out of phase with the top end using center tap as reference point. I feel the CEMF plays a big role in the inductive kick. Thanks great videos.
If you're still looking for the frequency, I believe it is 11.7728 Hz, this is the frequency that is in tune with the Earth, OU effects have been observed using this frequency and x2/3/4/etc
@@JenkoRun Thanks for getting back with great information.
It seems that this is a thermopile/condenser in one. Tesla worked a lot with steam and I'm thinking this was probably his way of recycling some of the lost heat energy. By passing steam through one coil and any heat-conducting liquid through the other, and the two being made of different metals, you can pull current out by the process of transferring heat from the steam to the coolant. Or you could probably achieve better results with no coolant at all and just a solid metal drawing the heat off. Copper tubing and aluminum, for example, with two metals shaped to touch with the greatest amount of area, flat bar and tube flattened on one side, for example. And water and steam flow would increase current. I'm not sure if my idea would even work however, as a thermocouple requires a heat differential between two connections. But that may also be the magic of this coil, perhaps he found a way to turn such a connection into a very long thermocouple that produces like a thermopile. Or, perhaps it is a capacitor fed by a special thermocouple. Another possibility is steam through one and the condensed fluid through the other in the opposite direction. Thus the temperature difference as well as opposing fluid directions would generate current and with an electric insulator but heat conducting layer between, build a voltage to be drained off. But I'm just throwing mush to see what sticks for someone else. I don't know enough to speak with authority. It seems to me, a mere capacitor could not be what this is, but since he mentioned replacing a condenser, I'm thinking a thermocouple/capacitor charged by steam since it is also to replace a condenser.
So, I stumbled across this researching for a new electric guitar build.. From what I read in the comments and understood from the video this is supposed to be a capacitor that doesnt open the cirquit..
Capacitors in E-Guitars are mostly used in Tone knobs by "sending" higher frequencys to ground making it sound darker.. I'm wondering if one could install such a tesla-capacitor in place of other capacitors, (Im pretty sure thats possible) or if there would be other practical aplications for electric instruments...?
If you have any Ideas let me know
It could work for equalizers, but then the coil would need to be very big to work in audio frequencies. Since capacitors nowadays are cheap I would use that instead
Very interesting.
Great way of viewing the relationships. Have tried animating them, as all is on the move. Did Tesla try a Mobius like relationship? The system are elliptical, through a directional bias.
I dont know if Telsa tried a Mobius configuration
moebuis ribon is unilater object (mean is topology got only one face) so it's mean it's a pure resistive object without inductive this good to replace expensive non inductive resistor whend you must avoid inducting perturbation inorder to measure.
i from brasil, amazing video, the best.
obrigado
can't I just put both ends of the speaker wire to the hot side of the dc voltage and the end of the coil to the ground side or vice versa? Would that mean that the capacitance is between the winds instead of between the top coil and bottom coil?
the capacitance needs to be charged by the voltage difference of the windings, just like the plates of a capacitor
@@MasterIvo Thank you for your reply, that makes sense. Oh and may I ask what kind of power supply are you using? I apologize if it's in another video. I'm just using 12 v ac adapter, but it it's making a pulsed magnetic field of over 100mG at a foot or so.
And what happen if we have a magnet moving over the pancake coul will it induce unipolar energ as farsdsy ecplain with the water of the tsmise while he crossed a bridge wich mean generating little voltage but lots of amperage?

Very interesting
The Tesla bifilar coil is better understood by stretching it out from a spiral pancake into a cylinder. Then you can see that it is just a centre tapped bifilar coil and behaves like a close-coupled auto-transformer, which would normally have the two windings end-to-end, but in the bifilar version the windings form a double helix, with close coupling, just like the Tesla coil.
center tapped? nothing is connected there. the 2 windings are series connected, and this makes the voltage difference between the 2 close coupled windings as large as half of the voltage supplied.
When resonant, this voltage becomes high, and is able to charge the capacity between its windings.
making it able to store very high amounts of energy it its fields.
this high voltage field then can be disrupted by introducing impulses (fast voltage changes).
this is done by making the coil series resonant (low impedance) and discharging (inductive spikes) a pulsed coil through it.
these rapid changes in the high voltage field introduce effects that regular science has never researched.
A regular unifilar Tesla coil, driven dual resonant, does not do this.
Very interesting idea, higher voltage increacing capacitance,. no wonder he used them to drive the secodnary and terceriary winign of his tesla coils, to allow greater spikes and discharges, vs expensive regular capacitors.
especially as the field collapses itd help give the shove to the top of the tesla coil and electron bank, /dome at the top to radiate out
so fare I understand this but what is the bifilar ore try filar maximul load? how calculate that?and with diderent types of materials like copoer,aluminum,steel wire? I mean how calculate how much those wire can carie curent and volteg in safe range and not to fry those wires?
how sheat metal behaves?
don't calculate, just experiment, see the heat with an thermal camera
just when I thought tela did not have capacitors,,, coil caps. how can we use them today?
see my april 2019 "radiant power" video for that
good job
thanks
Very good videos
can the aether be "magnetized" or activated to 0 permeability? is there a practical energy level or process?
it can be magnetised, but zero permeability? No don't think so, but maybe...
Build it and you'll see! The patent is for a novel component, a "Coil-pacitor," a resonant coil with immense capacitance. Boring? Simple? Not exactly.
Any Tesla secondary-coil can do the same as this invention. But this one is VERY SMALL. It's a miniaturized version ...low frequency without meters-wide secondary coils. High stored joules, but in a tiny package. A novel discovery.
If it also has any weird physics hidden inside, that's a bonus. But that's not needed.
The trouble with VLF-band high-power devices is that they're HUGE. Put them under oil, for high megavolts, and they still must be large in order to attain low-freq resonance.
How do radio companies do the same? Make the VLF resonators physically small? They add an external HV capacitor, which introduces all sorts of problems, as well as being a large added component.
Tesla does it differently: distributing the added capacitor all through the inside of his secondary pancake-coil. (Note that we could build a cylinder-version too.) These are power-processing devices, intended for pulses at high rep-rate, for high average wattage in a very small package.
If Tesla was inventing 100HP systems to go inside aircraft, or in vehicles and trains, or even human-carried, then SMALL WEIGHT IS EVERYTHING. (Note that 100HP is roughly 100 kilowatts. Can you build a 100KW tesla coil that's the size of a car engine? This patent shows us how.)
On the other hand, this device really needs to be submerged under oil, to attain immense voltage. After all, the first HV end is being placed next to the low-volt terminal, before spiralling back in as the second half of the winding. Build a copper-foil pancake TC, with close-spaced turns, in a small box under Tesla's "boiled linseed oil."
Very well expressed! Don't forget, when this coil is made series resonant, it can produces immense voltages, which if interrupted by an impulse creates a huge longitudinal wave form. More on that in my next video.
Sick
Very nice video
Very cool... but the phase of the dielectric and magnetic as they change... and how external fields interact is where the real magic is... can you animate the 3D?
For example, as using this as an electromagnet in a motor, a changing magnetic field does not produce the standard Lenz law effect. And as changing electric current flows through the flux-capacitor, it acts as a series LC circuit with the C dominating with it dumping first into the wire, then the current flowing and producing the magnetic field... which sustains the C... net effect, resistance... with the potential for resonance, or negative resistance... Or do I have this wrong?
I wouldn't say your wrong, but we have different perspectives
Excellent _
thanks Ivo
Thanks Stanis :)
maakt clockwise or anti clockwise rotatie uit?Verder super goed uitgelegd met beelden.
Thanks, Ja maakt uit, centrifugaal of centripetaal, AEther wordt aangezogen of uit gestuwd.
Excellent information. well explained.. "following"
Thanks :)
Hi, I have an odd question, and maybe hard to imagin, i am trying to visualize what a magnetic field would look like if I have two bifiar coils wound together into one coil , and they have apossing charges through them, will they cancel each other out , how will the magnetic field interact with each other, thanks
magnet field is like a vortex, swirling around the coils, if they cancel, no vortex is formed. but this is just speculation. imagination is limited.
Nice start...your ready to roll grasshopper...
:)
He did show the coils being used in other patents and what they’re used for.
bifilar coils in patents? or do you mean the coils in the radiant energy patents, are bifilar (I think so)?
I'd say Earth ground connected on one side, big HARRP like antenna on the other, steel, maybe graphite plates on both sides of the coil connected to maybe an adjustable oscillator of some sort to light a bulb or power something.
The 1/2V at 12:00 on the capacitor symbol should be V. As labelled on the spiral version, the open connection on the blue is at potential V. Half way between the red and blue plates it should be 1/2V as shown on the spirals.
1/2V is correct, half way between bleu and red.
coil endings are V and 0
try placing two of these coils about two inches apart and ensure that the produce N to N in the middle. fields will then be crushed with an open space between them filled with uncharged Ether. No use coils plates in the middle area and see what you can get for energy. The flux and Ether start there flows from each side of the dipole outward then back to the opposite side.
Is it possible to replace capacitors in electronic circuit with equivalent performing bifilar pancake coils since both are capacitors?
I’m sure you know the answer but they are not just tractor devices exclusively, it is an inductor with a potential higher ‘capacity’ of tractor force, so it’s an LC by definition, based on, as stated in the patent, the other variables. One being pressure.
Not exactly, capacitors are good at blocking DC but will pass Ac without a problem, that's why you see a capacitor at the signal input of an amplifier... The coil is simply, what is known as today, an air core inductor.
But capacitor has a dialectic layer so does it imply the plastic of the wire make dielectric equivalent?
yes!
love you !
Nice video, I especially like the VR aspect though it's more like a chalkboard than a 3d animation.
Now compare the bifilar coil to the spiral vector inversion generator. :)
The "Spiral vector inversion generator"? :D
So... basically, this coil is an LC circuit in and of itself...?
Can this coil/ capacitor be made to induce a more efficient magnetic field?
not only that
Tesla discovered methods of utilizing the aether and creating longitudinal waves which they themselves [the aether] create a much great potential. The DC pulse of high potential does the work.
Very nice graphics. I'll say again what a different world we would live in if Nikola Tesla had been allowed to succeed.
If you use a twisted pair to make the bifilar coil will the radial line have more power
radial line? more power?
What about a bifilar toroid construction? Definitely more difficult, but perhaps more effective.
Yes, it's possible. but it could have some implications. as the inside is constricted (when you start working with impulses). Could be interesting
you have simplified what Tesla said in his patent. its a great work. i understand it better.
Hello Ivo, does a coil wound from two wires A-A1 and B-B1, but on a spool with core dimensions of 32mm diameter, 35mm length, and an outer diameter of 75mm, with connected ends A - B1 and free ends A1 - B, have the characteristics of a bifilar coil?
yes. if A and B are both at the same end, and A1 and B1 are both at the other end of the 2 windings.
the series connection will produce an increased voltage difference between the windings
@@MasterIvo Thank you for your response.
Pulsing this coil might affect the local gravitational field (as TT Brown found)?
kinda what i was thinking !
try it!
Pulsing this coil can make your food warm on an induction plate.
Pulse it u got a ufo
If stuff starts disapeering then you know its working 😮
