Yes the inductance does change when the magnets pass the pole. The one thing that you can not do in the machine is twist the wires. Now each wire in the main coil has it's own resistance so this is offset a little when it turns on sort of like a mag amp but pulsed DC or more like PWM because of the switching so I had to sit and tune it for maximum power low RPM.
This is a very tedious to do as if I did not get just right I could not self start the machine. No one posted a Video of me showing it at the convention yet but someone out there has it. When I would start it from a dead stop it would accelerate backwards and slam agents three magnetic fields and dead stop then leap forward right up to 16RPM's that is how I knew I had the timing right. You all have done excellent work on this group. But now I'm going to do something I always wanted to do with a new machine just like this we must make it run with no input. Great group glad I could be here.

You go John! Running with no input? That's what I'm talking about!
I think I speak for everyone when I say, "THAT IS AWESOME!!!"

Cheaper per pound than the normal 11 lb. spools that everybody carries.
All we lack is to get over that last little hurdle of confidence to pull the trigger on a potential $1500 purchase. We both have different interpretations of all the information that has been presented by you and others here. I think that there are only 2 wires (2 - #15) on the center coil and he thinks that there are 4 wires (2 - #15 and 2 - #18). Then of course there is the whole thing about half the impedance.
Any interest in proving one of us wrong?
Thanks again for your help last night!

You should find your answer to how the main coil is wound in this post:

I have read through all the posts numerous times...
This is the same post that JB says to use a reed, which he has said on several occasions that he doesn't use any! Makes me think! Maybe that's my problem. Over analyzing!
Thanks, Brent

Brent,
You both may have different interpretations but, I'm telling you the center coil has four wires on it. The two outer coils have one wire each and that they are all hooked in parallel to form one inductor.
Big coil two #15 wires two #18 wires.
Small coils both coils # 15 wires.

John B,
Well, don't I feel like a heel...
Thanks for the clarity! I'm sure I won't hear the end of it tomorrow from Scott! Told you so...told you so!
@Dave
I owe you an apology. Forgive my ignorance!
Now on to the good stuff,
Brent

In fact it looks like the dwell is a directly proportional relationship to that latency between these coils?

Alright, I'm on my way to sleep but thought that redirecting "thinking" folks to this post might be worth somebody's time seeing that so much clarification has just come about.

Hope this is as helpful to everybody else on how coil windings are used,

Hey Gene,
Great work and good video! I'm still learning as I go and trying different things.
The PIC mods I mentioned will take a back seat until I get it working analog first. Mucho to learn!
I think John B has made it pretty clear how all 3 coils and all of their windings are hooked up now. Of course he did mention also that you could take one of the thinner (#18) windings from the main coil and apply some DC bias (reverse) to it. I'm guessing that this will get the main coil in the "zone" before the passing rotor magnets of the slave coils bias the main coil a little more. I think this is why the slave coils are past the core in relation to the main coil being at TDC.
I think I will add the slave coils and try all windings in parallel firstly, then try the DC bias tip.

I built me a magnetic amplifier to learn and study from. Its here in this youtube vid I put up last friday.
YouTube - 1000 Watt Magnetic Amplifier running 500 watts of lamps.
A basic Mag amp needs one AC winding and one Control winding which is controlled with DC power. (or so the mag-amp book says.) However theres a homemade mag-amp site on the sparkbangbuzz site that is what I made use of to build my mag-amp using 3 of the same model 1000va transformers.
In effect only one of the transformers is the load transformer. The other two transformers are used to create an asymetry on ONE side of the output load transformer. The other side of the output from the load transformer goes directly to the load. The two transformers are wired up on the other end of the load winding in series and finally out to the load. The DC bias of those two trafos (short for transformers) is then wired in "BFCEC" which means bifilar common end connected, which nulls the inductance of the two windings put in such relation or would if they shared a common axis and core, however in this instance it just seems to make it so the bias winding can't be shorted to cause the AC load to be powered. If you short the bias winding and the load gets power, then the DC bias windings are connected wrongly.
The interesting thing about a magnetic amp is that it "switches current". The voltage sine wave is always present on the load trafos output winding so that if you put a resistive lamp load over the winding, the sine will go flat as there is no CURRENT there to keep the sine from sagging. What happens if you use a cap as the load? I don't yet know, but will soon.
The idea is that the cap won't act as a short to the load so the full sine should still be let thru but the rate of charge would be based on the amount of current needed to bring up the rated farad capacity of the cap to the volts being output from the load trafo.
This then brought me to think about chopping the DC pulse bias. So I did that. I found that I need an ON duty of about 98% to get full output from the trafos load winding. (this without the cap on the DC bias to hold the charge, which I think might change the DUTY a little ... hopefully.) I need to add a cap there and see if it doesn't allow me to reduce the ON duty further while still being able to retain the output from the mag-amps load winding at full voltage. (albeit chopped).
So Chopping the DC bias on this mag-amp made little improvement over the power needed to turn it on or off. I am almost just as well able to use the DC bias in constant on as theres not much savings in pulsing/chopping the DC bias pulses if I still want the full rated volts output in the sine.
Thats my study of the magnetic amp I built on my bench so far. Thoughts/comments? how does this apply to the ferris wheel setup?
Seeing as the SG is a rotary magnetic amplifier that switches on a single polarity, perhaps the field shaping of the rotor is getting the waveform to trigger the drive circuit just right so that its better able to work with the now biased sine waveform that appears to be emitting a single polarity ramped over time versus the sudden drop to zero perceived as the field reguaging function on the typical SG perhaps? The balanced sine wave has the same time to drop to zero as it took to get from zero to the peak. The biased waveform presented in Nvissers vid shows that the neo has altered this sine into more of a sawtooth wave.
Good stuff... Hope I'm not off-topic sharing the mag-amp I mocked up.
Take care all,
Gene

Here's the pdf of the Magnetic Amplifiers book. The section on three legged amplifiers is what we need to understand I believe.

@all,
I want you guys to do a measurement, but first go look on youtube under air batteries you will run across LaserSaber showing how to make. That is not important thing even if it fun to do and will work in an emergency situation. Watch all the videos he has made under building a stubblefield coil, he has done some good work. Why he has stopped his research I have no Idea or the forum has just died for some reason. I was going to get in there and make some suggestions but I'm not going to deal with that right now.
This really applies to what your doing. The stubblefield coil is much more then people suspect as Peter and I have done years of research on Stubblefield. LidMotor has also reproduced this machine. I have built these coils but only used them for transmitting although I did see the effect many times with a compass.
I do not know what I was thinking at the time but I have run some simulations and have come to the conclusion that it can be done at a much bigger level however there is an art to building this coil. Very close to the monopole coil but with one iron wire.
The problem would be that the galvanic action takes over but that is not the important thing here. The most important thing is the Iron wire and what happens here. This is telling you something about where the Zero point energy is. This is the reason I'm doing this special switch as the output can be boosted to hundreds of volts to charge batteries. So just take the time to watch his experiment and see if you come to the same conclusion that I did. I think this will explain it. YouTube - Stubblefield Electromagnet Effects?
See if you see what I see................

Coil calculations
All,
Has anyone attempted the mathematical computation of the impedance for the bottom coils based on what John B has shared with us so far?
Here is what we know…
1) Total impedance = 12.6 for the three coils
2) Center coil 200 lbs. with 4000 turns
3) Slave coils are 1/2 the impedance of the center coil
4) All the coils are hooked in parallel to form one inductor
5) And as of last night, we now know the wire sizes and number of windings for each coil
If you take the calculations (inductors in parallel) that were provided by Jeremy…
Slave Center Slave
31.5 63.0 31.5 = 12.6
You get approximately 10,000 ft. (100 lbs.) of #15 on each slave coil = 31.5 ohms
(all numbers calculated from the Essex Wire engineering data sheets)
The center coil is more difficult to determine. Are the power windings in series as Jeremy has suggested? Are the windings all the same length?
I took a stab at it today with not much success. All my calculations come in at well above the 200 lb. mark. Way above! Try and get four wires in parallel to equal 63 Ohms…not easy. Is there more to it. Anyone?

How can I help you. did you get it running? I would study my coils as I said the coils are two different impedances and that the coil must be big in the center double the outside coils I could measure them if you want.
John
I'll take you up on that offer if no one else is interested!!!

I was wondering if this were ever going to get into N.Stubblefield. John is this what described by ED as "I have a generator that produces currents on a small scale......"?

Brent,
What is that you want to know, your very close to the answer. Each big coil took two buckets of wire #15 so that is a little over 200 lbs. Now since I have been working on something much different if memory serve me right one bucket of wire was 125 ohms not very much power at 12 volts, so 36V
Now you must also add in the two number 18 wires that was two buckets.
So yes you are very close. Now Back to the stubblefield coil that I point out. REDrichie, Yes that is what Ed was talking about. watch the video very careful. You may not need any battery, it's the switch that is important with that much wire. A reed will just blow up.
