Rotating Magnetic Field's and Inductors.

Looking at your pic's,and the twist direction of the string,the magnets in your video were spinning in the correct direction to untwist the string.
One easy way to verify what is going on,is to lower your spinning magnets so as they are about 1mm of the floor. Then let the magnets spin. If the magnets touch the floor after some time of spinning,then you know the string was unwinding,and getting longer. If the distance between the magnets and floor increases,then you and woopy will kicking back on a tropical island in no time flat.

I believe that what you and woopy are seeing,is the force of gravity unwinding the string--nothing more.
I would love to be wrong on this though lol.

The string is winding itself up. It is not unwinding. I'll try the measure test tonight and have a look at Tk vids.

There is now light at the end of the tunnel.

Again-->As the south field of the magnet on my rotor approaches the core of the coil,it induces that field into the core. When the coil fires,it fires a !!north!! field at the end of the coil that is closest to the rotor.  You just said exactly what i have been saying for over three week's,and during that time,you !and Poynt! are trying to tell us all here that it is this !!cannot be seen!! reverse voltage across the coil that is the reason for the reduction in current draw during the ON time. Well in Poynt's Sym case,that is correct,as the I/out also went down<-- Your lenz's law.
But in my case,we have a situation where the I/in went down,but the I/out went up. If what you and Poynt are saying were true with my DUT,then we would have seen the same results Poynt showed,in that when the I/in was reduced,then the I/out would have also been reduced--but it was not-it increased.

So i hope you take some notice of your own words,and go and have a closer look at what is happening with my DUT. Try and be unbiased for once in your life MH.

Yes, you are frustrated, but the "try to be unbiased for once in your life" is hyperbole.  I express what I think I am seeing to the best of my ability.  There is no reason for me to be biased.  That's like when someone shows a dumb-ass experiment and says, "you must be a government agent" when you comment on it.  Why would a government agent be concerned with somebody showing an experiment that affects nothing and dates from about 1905?

I think that the idea that a coil could be clamped to a battery voltage and still have in induced EMF inside it from a changing external magnetic field is something that you did not understand and thus were incapable of conceiving.  Is that a true statement or not?

I don't think that you were aware of this.

The clue is to look at the current flow through the coil while it is clamped to the battery voltage.  If the current deviates from what it is "supposed" to be under these conditions then that can be explained by an induced EMF in the coil due to external factors.

So, that is one of the key factors in helping us understand what is going on.

If you accept Poynt's challenge, perhaps with a new setup with a more efficient coil and perhaps a better rotor, I implore you to make a timing diagram.   Poynt can do the same thing by just dropping virtual probes onto his schematic.  But if you want to get some real satisfaction and convey your points to your audience with efficiency and impact, a nice timing diagram that is annotated with short text descriptions will be way better than about 400 posts like we have right now.

Meanwhile there is a multi-billion dollar motor industry, and a multi-billion dollar magnetics industry out there that is leveraging off of 100+ years of accumulated knowledge. 

   To put it in context, I never heard Tesla's name mentioned once when I was in school, not once.  And the reason for that is Tesla's pioneering research is five human generations away from us, and who knows, something like 20 technological generations away from where we are right now.

You want to talk about the motor industry.  Then explain why these magnets that can do no work are now used in almost all small DC motors used in industry?  Why aren't they still using field coils?

Tesla is not mentioned for a very simple reason.  There are many who for whatever reason are rewriting history to reflect their agenda.  I did learn about Tesla in high school.  I learned of his fantastic genius and amazing engineering skills.  I am appalled to see how his name is misused today and only an extremely ignorant person would even attempt to minimize the great achievements he accomplished.

Something to consider when we are talking about a magnet biased core increasing induction....

By the book, the magnet is not moving and dragging its field across the windings.

But with the rotor moving the magnets fields are cutting the windings..

Consider a transformer. When we apply an ac input to the primary, the inductance is as high as it should be for that coil without the secondary loaded. But when we load the secondary we now have a moving field coming from other than the primary and it is said that the primary inductance will be lowered in that case.

So it is probably not a good thing to say for sure that the drive coils inductance is raised when the rotor magnet is in motion. Not yet anyway. In no way am I disputing the value of the rotor in the circuit as shown. But we may have to delve into it a bit more to see what is really going on since I got this Hantek scope. 

I put the motor setup from my vid showing the second stage coil running off of the bemf of the first drive coil, along with using the second stage bemf to charge a battery, back together..   Im going to start with examining the first stage bemf into a resistive load. I bought 8 20w 8ohm non inductive resistors from Radioshack and put them in parallel to give 1 ohm. Ill be using it in the future for current readings using the scope. I have some other gigits n coils I want to use in that old setup to test some theories I have on this subject. 

Just recently got my password for YT back in hand as I had forgot what it was for a bit due to not using YT much lately. So Ill post vids of what I want to see here. If thats ok. I tell ya, I miss the old YT.  Its not what it was, which was great.

While you may believe your hypothesis to be true, you have not demonstrated results that verify that hypothesis.

I must say Poynt,that you have not demonstrated or simulated the results that my DUT have shown either. Are you able to do that with your simulated replication of my DUT ?-->can you decrease the I/in-P/in,while increasing the I/out-P/out?.

I know you said you dont really have the time,but that could be seen as--i cant do it,or replicate Brads result's.

I have always been happy to carry out experiments as requested--even though MH seems to have missed the timing experiment results posted some time back on this thread. So i hope that would hold true for those that wish to dispute my claim's,and back up there dispute with experimental results that !do! simulate my results.
