not exactly what I was looking for.
But he shows nicely the motor effect.
I was looking more at driving one from a wind source
Or some other rotational power (sterling, or whatever)


A lot of his coils are multifilar, not necessarily 2
and it appears the lights are in series with the signal generator.
So it is unclear what generative effects (if any) are produced.


The magnet is free spinning, but I believe it is diametrically magnetized.
So it answers half of my question.


I’ll probably have to just wind one and experiment myself.
Never tried, these are usually powered coils.
But, I mean if we do it one way, we should be able to do it the other way.
The same as the receivers, but by generating our own oscillating field
Using permanent magnets.


I’m thinking more in terms of a horizontal transition of the magnets.
Crossing the center.
magnetic field will increase on the way in, and decrease on the way out
which (in my mind at least) seems like the perfect manipulation of the lenze/Lorentz
forces.
Actually it’s the simplistic version, the ideal case would be to approach from 360-degrees
Then retract. (just an idea, I haven’t performed any experiments, and have not yet
                       set up a series of equations to describe the actions of any particular magnet)


The ideal case presents itself with some mechanical difficulties that I’m not willing to tackle
at this time. (iris door?)


So I’m looking at n/s/n/s passing directly over the coil, from a rotary device.
in theory, each winding should act as an individual coil of its’ diameter.
My curiosity is in how it will interact with the magnet.
the attraction force will peak at the center, but as it leaves, is decreasing.
(or in the other viewpoint, the opposing force will be away from the center, then towards the center after)


the bifilar effects show the opposing field will be extended, but still diminishing with radial distance.
As long as the driving force is enough to overcome this, we should be able to generate with them directly.


What these videos DO show, is we can mount his set-up right to a bicycle or large wheel acting as a gear
of sorts, causing the cylindrical diametrically magnetized magnet to rotate
and in this manner it would be the same as my proposal,
but only using the center part of the coil, and not it’s greater outer periphery.


A very very large cylinder magnet, and a coil smaller than its diameter
would maybe work.

That’s a nice 20-amp homemade motor in the 2nd video.
Using lithium batteries it could probably fly.


If you stack bi-filar pancakes, I believe they need to be in
parallel, and have to line up vertically.
I’ve read about that situation from various sources.
Otherwise results in a completely different magnetic field.
With multiple vectoral components.


To increase voltage (in a generator), simply make them larger.
(this is of course within reason of the diameter of your man-made field)
