@all
OK let's start this thread already.
The best painters in the world have had years of experience mixing their colors to better understand their final effects which they then apply to their canvas as ART. We, as OUers, in the search of overunity need to rise to that same level of coiling proficiency which means we need to understand all the different facets of coil pulsing, topology, differences of topology to coil pulsing results, where are the bugs, how can they be fixed, etc, etc.
The Half Coil Syndrome (HCS) I am showing is a simple test designed to investigate the actual dispersion of any energy pulsed into a coil and how this coil will respond either air core or cored. Our general method of winding coils is more of a pot luck method where we have this mental image of a coil and then we strive to reproduce it in real life then we start pulsing away to figure out if there are any favorable anomalies that could be taken advantage of. This process is slow, chock full of minuscule checkmates that are very difficult to realize once the coil is made, understanding that a builder could be 5 turns or a coil tap away from some very special results but will never know or learn more about any such new effect.
It is basically for primary coils since this is the main means of driving the coupling to a secondary, or destined for drive coils on rotary magnetic wheels, but I will also be talking about our secondaries and how we can test things to see how better to remove the impress as output.
Hopefully this thread will help is elucidating these effects (and differences of effects) and provide builders with new alternatives to maximize our present coupling challenges

Thanks for your comments. My bench tests were conducted with many types of pick up coils and under AC or DC pulses and the same result was seen. My decision to stick with the tape head model is because it provides a good sliding surface and it provides the same basis for pointal comparison whereas with a coil it will always depend on the surface area and angle exposed and the area of influence.
@TinMan
Well my friend I have to thank you for your time and effort in producing your video of your experiments.
I would have hoped that for a first baseline someone would try the same type of test on the same type of simpler primary coil (air or core) just to corroborate that the effect is in fact real enough to warrant some much closer scrutiny into the effect. But no problem since in your particular coil which is a basic Tesla secondary pulsed as a primary, in the three tests you have generously shown using three types of pickups, a MOT secondary around the primary, a tape head and a small coil with a core. Let me say that in the last two instances we still see the HCS although in your case with such a long primary, we see something new, which will be a great new part of the HCS puzzle.
In your first test with the MOT coil, what I need to ask is if you can please do it again, but this time, set up the MOT so that you can move it further and further away from one end, then from the other. See how far you have to go until you get to half the scope rise you had before when it was sliding on the primary. Why you may ask. Well this will show me the width of the influence of your MOT pick up coil. What I think is happening is the MOT has such a wide receptive angle that when it is on an end, it catches not only the end but up to 1/4 inward or more, so when the MOT is over the end, one side is empty and your reading is lower then when you slide to center which now has both sides extended over the primary so you have maximum then you slide it to full left and it went to the same level as the start. This for me seems very normal of what we see there but this is more like an RMS'ing test and cannot confirm or negate the HCS effect on its own. You would need to use a three turn coil around the primary and slide it for a more pointal reading of the energy spread with such a pick up. But I would suspect you will find again that only half the coil is responsive.
The phase issue could be relevant to the fact that your Tesla coil is usually used as a step up secondary that is being pulsed as a primary hence from the moment the pulse occurs, there is a delay in how fast the low voltage can permeate the wire and raise the current, as you see it all as off phase. When you take off the cap and see the jagged rises, that will be a clue since going up and down makes a delay in the total rise. If you tried a simpler primary, maybe it will go away. hahahaha
One of the reasons I call this a "syndrome" is because we almost have to make a diagnosis in every case, but in general then, call it E field, B field, H field, I just call it "magnetic influence" because for me right now, that's the only real proof on Earth. There is a magnetic influence but we do not know if there is in fact a field involved or not. Leaving it as influence means the cause is and will remain open for years to come. In my case, the cause and effect is due to spin conveyance but regardless, this does not have to hinder the advancement where if there is a positive diagnosis, then we can confirm there is in fact a coil sickness, and now we can work on remedies. Like Dr.Phil says " You can't fix what you don't acknowledge".
For me, the primary coil eats up prime real estate on our cores. Let's say you wind 10 turns of primary on the center of a gaped E core. 5 turns on one side, then continue over the gap with 5 turns on the other side and now you pulse the entire primary. So how is the energy dispersed across the 10 turns? If it suffers from HCS, the first 5 turns will dissipate about 75% and the last 5 turns will dissipate about 25% of the total pulse. If this is the effect you were looking for, great, but chances are it's not. We spend so much time on pulse circuits and so little time on the actual action in the coil that it seems very counter-productive to do so much, then to abdicate the coil to its own devices. So we need to find ways to increase the punch since losing here is not an option if you are looking for OU. hehehe
One remedy is to add a second (or third in @gotoluc's case) primary coil on a transformer but off the main device and whatever that coil produces as output can be returned to source so very little added overhead. You are basically putting back around 25%, working the device with 75% but now the primary has full dispersion over the core. This is were we need to be to move forward. I'll show a video on this soon.
So what @TinMan showed is it's easy to test these small things in your builds and discover the finer nuances for yourselves.
More soon but if any one has comments please do.
