By using 2 separate bifilar coils its possible to get equal currents travelling in opposite directions on the same core simultaneously, cancelling the field produced by load current draw. So output volts are doubled whilst Lenz effect is cancelled. Back EMF harvesting is still available.
You have just discovered Teslas DC Puls Technology in your setup. There is a good video on youtube were John Bedini explains Teslas idea. Search for: Bedini ful 1 / 11
The reason your diode is heating up is due to the thickness of the wire on the pulse coil, thicker the wire more current less voltage, thinner wire more voltage less current.
When I compare two coils with the SAME resistance BUT one coil with thin wire and the other with thick wire, my conclusion is that the VOLTAGE of the back emf is dependent on the LENGHT of the wire and the resulting AMPS come from its THICKNESS. My first personal measurements are indicating that the back emf does not get noticeably stronger once the input current (input voltage divided by the wire resistance) gets bigger than 1 Amp.
That is an interesting theory, I will test your theory as soon as I get a chance. My Big coils as I call them are less than 1 ohm each and in a couple of my vids I put 3 of them together in parallel, bringing the total ohms down to 0.14 ohm. I have run them at 1.2v all the way to 5.1v and the back emf increased as I raised the voltage to them. So at this time I have to disagree, But I will do a vid that proves it. =]
Just from the numbers you give it is clear that my theory is bul* shi*. But still I find it most important to find the relationship between input and back emf in relationship to the wire lenght and in relationship to wire thickness. Any idea?
I agree that the length of the wire will have a given resonance, just as in antenna wave lengths and such.
But here, we are not necessarily working with radio freq, but maybe with the bemf pulse. That I will study later. I do believe that the back emf is of a high freq pulse due to the collapse of the magnetic field once the power is taken away from the coil. At what freq, I dont know yet. Light speed? Thats pretty high in freq. I do know that an iron core can slow down the collapse...
So air core will have the highest speed collapse of all, there by producing a very quick bemf pulse, of which the speed of the collapsing magnetic field passing back through the coil should produce more bemf per power used to produce the initial field.
Makes sence - it explains why iron core transformers loose there efficency when the frequency is raised. This may be the reason why Tesla never used iron cores.
Eventually I will get into Tesla type setups. I am very interested in Don Smiths device which is basically a Tesla coil setup but the primary is in the center of the secondary in which he claims will amplify the POWER not just the voltage. Imagine using a 12v bat to run a smaller neon transformer ans the output can run a whole house! Air cores my friend. The Tesla advantage.
Pure Teslas invention. In Don Smiths version there are only some resistors added for tuning. But there are still some interesting thoughts about how to harnest magnetic felds more efficent.
Do you happen to remember where you read about Tesla talking about bi-filler coils??
I would like to read that for myself!
Great work!!
As far as the "big coils" Bedini and Bearden claim that this negative energy travels on the skin of the wire or perhaps through the plastic insulation, either way bigger wire would have more skin and or more insulation to travel through. Have you watched the energy from the vacuum series, where Bedini lights a neon on the plastic of a car battery?
Look for teslas pat. on bifi's he explains, but I dont get it yet. I have some writings on him in a debate on this stuff, i will have to find that or the link.
I was thinking the same thing on the "skin effect", being that the larger wire has more skin. My next project is to wind multiple fine wires that equal the big stuff in awg and it should have even more skin and we will see if thats the case. We are on the same track. =]

Hi... Have you got any idea, how to improove efficiency of standard magnet 3-phase generators with capture bemf?

very interested to see the results on that last coil you show here. Very interesting Magluvin.

Has for your bifilar coil, I've seen this where they use a ferrite core to tune it to resonance.

Hey Z
I hear ya, but is there any advantages at resonance compared to a normal coil.

Hi Mags. As far as mutual inductance from one coil to the other is concerned, I would say the answer is yes.

Back emf saturation: V / R > 1A
What do you think?
TheGuru2You 2 years ago
Hi Guru.
Well I think you've just answered what I said, but in a different way.
One is a trade off against the other.
Mags is using a thick single coil for the pulse coil and using a diode in revers to capture the bemf off that single coil in this experiment.
cheers Z.

Hi Stefan.
I don't realy hold with this formula V / R = 1A
This only holds true when sticking to the
1 times table, such as
1V X 1ΏR= 1A.
But if you do this calculation with 2v x 2ΏR= 4A
and not 2A
as it would if you used 2V X 1ΏR= 2A
cheers Z.

My theory
I said:
Back emf saturation reached when input: V / R > 1A
Meaning a 12 Ohm Coil would produce most back emf when given 12 Volt input. Higher input voltage will not inrcease the back emf.

Also an iron core can slow down the build of the field as power is applied.

Iron cores have their advantages also, but each have their place for a desired outcome.
