The reason I was not expecting a sawtooth waveform, see picture below, excuse the image, it is just a rough analogy

If someone could confirm or show the field shape to be different please?

The way I figure it, the scope readings should have given sharp dips for point A and B

Edited: Nevermind looked over Lumens later graphs, back to the drawing board!

Re effects and reverse spin.

Which should mean that points A and B must be passing the field sensor at the quickest, and the 90 degree opposite maximum poles at the slowest speed.

Would it be right to assume also that points A and B are at the saw-tooth peaks?

No, they should be nulls, points A and B are where north and south theoretically should be canceling each other out.

Re Sawtooth wave, Just going through all the sink science vids. Not sure if it is relevant but he does one with six balls. They bounce out and come back in again. It is not quite a sawtooth but close.

Also check out the magnetic liquid vids for some interesting patterns. I will try to find them and post later to save you time.

Thanks RB, I'll think more, I have to look over Lumens later graphs again.

I know little about using coils to measure magnetic fields, thanks for your replies.

@PolyMatrix,

That's interesting but don't know this applies to the present study. @RunningBare's and @Lumen's approach is also interesting and may give further insight into what's happening and what to emphasize in the replication. I'd again point to the following video as well: http://www.youtube.com/watch?v=tknwdltnB6s .

We would really wanna know what the exact form of the rotor and stator fields are in @alsetalokin's video as well as their mutual disposition and ratio. It would be interesting if he can still demonstrate the effect of acceleration we see in that video. Also, if he can make another rig just like the one in the video and demonstrate the same effect of acceleration. Could it be that that was just a fluke which he came upon just fortuitously? It's sad that, although seemingly more cooperative than many others who have disappeared without a trace after making similar claims, he isn't forthcoming enough on these issues and we have to play a guessing game.

Make your on Feromagnetic fluid (Not recomended and toner gets everywhere!)

This is the one I was thinking about in association with the @AL-rotorwheel.

@ Omnibus

Also using the fluid maybe a help in analysis of what is happening.

@PolyMatrix,

I wonder how reproducible the patterns are so that they can be used as "fingerprints" of the magnets in a particular contraption. If so, successful rigs will be characterized by their own patterns which anyone trying to replicate the device should be vying to achieve first.
