Toroidal Coils

[mx1000]

Isn't it necessary to have expert level precision in this ?
So that the Toroidal coil is almost exact (99%) ?

Also what you expect to find or is this just peek and poke ?

Sincerely.

Somewhat; but I do figure nature isn't a 99% perfect engineer. 


What I was looking for was anomalies; but given that I'm working with stuff engineered on not the magnetic flow, but electron flow, maybe it's impossible; 


99% is pretty easy to do... 1% deviation in the frequency though will result in beats... But yes, if every part was 100% perfect, then I would have less losses.  Each coil addition resulted in less apparent power; and occasionally I would switch back to a sine wave, and if I got near similar power out, it was definatly a good balance, a square wave will trigger near harmonic frequencies better than a sine wave.  At the end, the power output from a sine wave was quite a percentage less than a square wave input.


I got a little sidetracked tracking non anomalous behavior; and other than being able to create a DC bias I've not found anything specifically; other than these coils self induct much better than any other geometry.  (closer to a K of 1)


So other than recording the notes along the way; I'd love input from others on how to discover anomolies


-----------
Additional note that I should include again; a lower resistance (impedance?) load will take more of the energy and leave less for the remaining circuits.

Tinkering with resonance

The tiny coils are resonsant at 3Mhz without a ferous core.

I was considering toploading my coils.... and tried adding some ball bearings; covering the wire end with insulation....

I also started attaching croc-clips so the wire goes into the middle of them instead of just across leaving the pointy wire sticking into air, and improved behavior a slight amount I think.

for each active coil, it is possible to add another coil stacked on the first.  But the distance of 1 coil will not be close enough to get a good voltage without a active coil between.  Active coils have a active current path or an active load.  They can be grounded on one side and use the load on the other back to ground, or separate attached to different polarities of load to a common ground.  If an intervening coil loses its load, the others stacked on top become inactive (FAR out of resonance). maybe that's wrong...

was adding as 'extra-coils' to the topload....

these have been far easier to experiment with resonance than any other coils; for peer induction, stacking works well in a consolidated space, and can be put on a spindle or rod to keep better alignment.

So continued experimentation, and seeing a effective core applied to the lynx wind LJL (?) as a closed loop around the outside of a short arc of the coil, I applied that idea, and built up a system that would induct higher voltage than the source at a high enough frequency that a short across an incandescent load worked.


I later applied the mazzilli to a standard 120-25V (1:5) transformer.  With just about any capacitance it triggers oscillation at 50-60hz.  So the design of the magnetic characteristics and its inductances must be such that the field collapses in time; I got power output, but it was VERY flickery.  I was able to put it across a bridge rectifier into a cap and draw more of a DC current and get a stable output. 


Inbetween, I removed the core and was able to get the system to work the same, but at a slightly higher voltage, and higher frequency.


But I find that adding and subtracting loads adds and removes amps appropriately.  Almost to the point that the oscillator itself consumes only 10mA.


I can definatly see improving the number of turns (maybe wind it with 12x the filaments) to get a appreciable voltage out from the same sort of current.  But it is still power, if that voltage is tapped can only draw a small load off of it.  Like say 1000 LEDs in series, they only require 20mA, but use some voltage.


Above that another coil to pickup stray field begins to influence the primary coil's resonance.  Earlier observations at low voltage high frequency, that the target inductance affected the resonant frequency more than the driving inductance; being of similar inductance, (60uH and 72uH) they aren't dissimilar enough to cause a significant disbalance.


I tried adding various idler loops... that is just a loop that is resonant with the rest... but that only seemed to consume power, being in essence just a larger weight to have to swing, rather than being collaborative... that is a larger weight to have to change direction of.   


I dunno I've tried to consider when the induction happens... it's both as the current rises and falls, and the opposing current is opposite in greatest effect; although that's not really true.  If the ground is connected on the same side of the positive signal, no output registers; although there should be a negative potential formed at the other end....


So then I remove the core; then I removed the idea of being two separate coils being grounded, and shorted the ends that were grounded, and still get a good differential.  This winding is a caduceus.... it goes clockwise to the top and clockwise back to the bottom... although compressed; so the current flowing in these windings is in opposite directions, which is least issue for their own fields; since they want to induce a current in near windings in that direction direction the current is already going (except it's kind of a messy winding so I'm not sure that really counts)
... but it's not caduceus because it's not spread/dialated, it's just a winding in one direction to the end, and back in the opposite direction on a second layer; only every winding is passed through every other winding.


But this is really only one dimensional...



manipulating the shape of the pickup coil has little effect... although modifies the frequency slightly.


So I have an oscillation; even if the rodin makes a 'vortex' this vortex collapses at each cycle.  a DC vortex would ... nevermind...


So, the field builds, being built from a current flowing through a wire.  A coil's caracteristic is also to impart a momentum to the flow... but err anyway, so the current flows, a field builds, and is a differential(hmm delta) per point in space, and crosses other conductors.  It's only the (expanding) and (contracting) fields from the source ... more Amps per meter yields more tesla, or flux ... that's more electrons moving for a larger composite field?  That's more electrons aligned in a similar direction to build a composite field?


... but more ..


Also there is resonance, and there is resonance... is there a significance to 8 octaves?  maybe it's 9 octaves... I should compute that when I fix the info on the video...


even if there is a resonance to the fields of the nuclear fields of the atom, that's just going to be the same up/down.  The field can be sustained by continuing to supply amps.  But if you Stop the amps, and allow the field to collapse, the action there imparts motion to electrons in near conductors, still in the opposite direction, but in its own conductor in the same direction; being a momentum of sorts... so is it the stopping of the mass of the electron part what pulls the field back down? 


There's lots of ways to model magnetism with analogies, but none of them really are right.... a whole lot of words to explain nothing


(added pictures... frequency progression, as load capacitor charges)
state 1; some 5Mhz frequency.
state 2; combined composite out target low frequency and high 5Mhz frequency
state 3; 240Khz frequency, higher power output.  20x frequency difference (20.8333 if use 240 instead of 250, but the top end was inexact, but was 5.0(8?)Mhz... so maybe 21x?  probably not as low as 18x... which would be a 3, 3, 2, instead of 2*2*5(20)

Looks like your spending alot of time and working it out, very commendable and thanks for sharing.
My day job is very demanding at the moment so not alot of time to spend doing actual experiments for now, but it gives me time to think.

If we look at a simple transformer step up, step down it doesnt matter, look at how ac pulses each side of the primary, the winding direction from each side.

Ac works with the bemf of a coil, but there is a drawback it changes the polarity of the core.
