3D electromagnetic field

[quantumuppercut]

As i have pointed out right after testing the capacitive coil, the measured capacitance is in the low nanofarad range.
While this reading might allow to determine the approximate range, i am aware of the fact that an LCR meter is not made to measure coil capacitance.

I have also tried series caps to increase the capacitance, but that did not
yield more,because the coil's own capacitance (area of opposed plates)
is what limits the received energy.
I suspect for such a coil to yield higher output it would have to be physically large or maybe wound with flat copper-sheets/stripes.

If you put a series cap in addition to the open bifilar, then whatever lower capacitance would dominate the loop in my opinion. I quit using wire capacitance and go straight for series cap because I know you mention nanofarad wire capacitance. We need wattage.

Hey mondrasek, that's very interesting information. Thanks.

Hi there,

Here is someone else's diagram of a capacitive coil, used by quantumuppercut in the Romero thread. This is one way to create it, the winding is the same but the connections are different. If the red was connected to red and blue to blue that is the way I would connect it, there is no connection other than capacitive.

You can use this as a drive coil and a generator coil, there will not be a Lenze effect.

Mike, if we connect the red to red and the blue to blue I think we end up with two shorted coils on one core. This creates full Lenz drag on the rotor (at least in my case).

When I try quantumuppercut's idea I end up with a wave form that even more closely resembles RomeroUK's posted O-scope pictures if taken dirrectly from a single coil. Unfortunately, after rectifying that wave form it does not want to charge the large Dump Cap except very slowly. So attaching any load kills the output V immediately.

Obviously I am not qualified to second guess anyone's concepts in this arena. I'm just stating what I have observed. So if you have any guidance or explanations I would welcome them.

If i interpret that imageshack diagram right it is like my first coil
Bifilar wound close to each other and with the ends open circuit?
It is even important at what end of the coil you attach the scope.
Voltage at one end is lower than at the other.
I noticed if i short circuit that coil 1s to 1e and 2s to 2e ,the voltage collapses by 80%.

I must admitt to being a little lost.

P.S.

A P.S.

You really need to test this on a rotor, if you get it to run then it will charge as well.

Okay i must clarify something about the coils.
I have not used them in capacitive mode.
The eh-antenna pdf depicts an Hz-aerial which shows 2 connected bucking coils.



I used that.
Just tried it again using the 2 shorted coils as capacitor
and there is just some tiny spikes but no mentionable voltage
measurable across the 2 coils.
The capacitance between the 2 coils would be also fairly low.

In post #57, Mike states:

Wind a bifiler coil, the start of one wire will be 1s and the other 2s, the finish ends will be 1f and 2f. Now connect 1s and 1f together and 2s and 2f together. what you have made is two coils with a capacitance built in joining them together. We do not want an antenna, we want a magnetic coil with a vortex field and this is one way to do it.

That was the coil of my first experiment.
Since the windings are tightly together you do get a bigger capacitance.
But contrary to what Mike suggests in post #33

It is ALL in winding the coils in ANTIPHASE to create a unique vortex field

that coil is not technically wound in antiphase.

The only possible approach to wind 2 antiphase coils that exhibit at least some inter-winding capacitance would be
to wind them in layers ontop of each other.
Coil1 Layer 1,3,5...
Coil2 Layer 2,4,6...

and have a huge amount of turns,so the area increases the capacitance somewhat, but unfortunately
i don't expect that capacitance to stay in the nanofarad range, which would not really promise huge charges.

Okay i made the same test with a copper rod as core.
The rotor slows down when you bring the coils closer to it.
Loading it (short circuit) does then only very very minimaly reduce the RPM.
Even open circuit the rotor slows down.
Looks like there is lots of electrons moving in the copper )
So i tried the same test without any core and the
voltage is higher than with the copper core and there is NO slow-down
when you bring the coils close to the rotor.
Loading also does not seem to affect RPM.
It needs to be said that i have only used a couple of turns on the coils.
This needs to be tested also with a higher inductance
and then compared to the ferrite cored version and most importantly to
an single air-core coil of the same inductance to see if there
is any unusual gain/difference at all.

Thank you for your thinking and experimenting, this is what I wanted people to do, "to find out for themselves but with a bit of guidence.

Now what have you found? the two air coils have stored a high voltage through "capacitance" that is the two windings having a reasonable capacitance between them. This does not slow the rotor either open or under load. Is this what we want, "yes", zero Lenze as I have stated.

If you use a ferrite core the same can happen only if the saturation of the core is controlled, if you don't then you have lost the advantage and Lenze will rear his ugly head again.

Timing has to be perfect and with perfect timing we can use that stored energy before it is being charged again. We need that energy "from one coil setup" to do two things, one to switch the mosfet and the other to supply the power to a secound or more coil setups.

A mosfet will need X amount to trigger the gate, so we only take X amount, how?, use a zener diode for the exact requirements of your mosfet and NO MORE. The rest of the energy goes to the other coil setup or setups. Your coil capacitor is now empty and ready for another high voltage charge without Lenze coming to stick the boot in again

You are getting there, I feel it.

Another thing is if you use copper or aluminium as a core it has to be connected so as it is part of the capacitor "it has to be drained of it's electrical charge or again Lenze puts the boot in again

MonsieurM,

I should have been more specific--non-ferromagentic material, but still conductive so electrons in the material flow in response to the field. Hence a metal like copper or aluminum or perhaps carbon.

S

sorry for that

I guess then I have to shorten the list:

non-ferromagnetic conductive substances : , copper aluminium, air and water and maybe graphene....Tesla...

Xenomorph,

I've read through the material on EH-antenna.com a number of times. From my reading of the material, the core is supposed to be conducting, but non-ferromagentic. Copper or aluminum should fit the bill. In addition, I believe their HZ antenna has two coils wound in the same direction on the conductive, non-ferromagnetic core separated by a small gap. I've been planning on building my own version of this, but haven't had time this week due to work demands...

I'd be curious if you get a chance to build such a beast if it displays any different types of behavior.

Hey Skaght.
Okay i will try to make a copper or aluminum core.
Concerning the winding direction, i believe Mike has mentioned in one of hist posts antiphase and/or opposing windings, but i could be wrong.
The ferrite-less version will certainly also have less of a Lenz drag, because whatever current might still flow could not be amplified by the non-magnetic core as much.
But the favourable result would be of course to have no electrons moving.
I might just wind 2 coil pairs one with opposing winding direction and one without just to cover all cases.
The aluminum core aspect together with antiphase windings reminds me remotely of the Genesis project, but that was a different principle.
