I realize you are not making any claims, but obviously the
grain of the wooden bowl is operating as a "chaotic attractor"
for the motion of the rotor. Still it looks neat.

Hi, One of the things I am going to try after the novelty wears off is to construct a wire grid around the entire outside of the wood bowl.
The spinning magnet field would have to cut through the wires.  Then If I can get the ball/magnet assembly to spin again I would measure the ?? crazy output.  What kind of bench meter would be best suited to do this?

I think if you want to read volts generated in the pick up coil wires, a scope would be best at first, to see what the output waveform looks like; And perhaps also try the coil loaded with like 100 Ohms, 10 Ohms and shorted... And check the current in the de-gauss coil for each load case; for calculating energy efficiency.

I also suspect there would be 2 or 3 main problems:

The first might be getting the coil mesh close enough to the moving mags to generate any real power. Also this new generated field will probably  throw off the magnets' trajectories in some unpredictable way when under load. If the mags could be made to move in a consistent circular path somehow (like on a constant track); it would probably be easier to get better power output results from the mesh coil as it's geometry could then more closely match the mag's path, and so the coil could be moved closer to the mags' steady orbit, and so generate more watts.

The other problem, would be trying to isolate the pick-up coil from inductive coupling interaction with the main energizing degaussing coil. So you might need some kind of a shielding between the two coils to see what is really going on, to keep them from acting like a transformer (as those degaussing coils can put out a hell of a strong field even several inches away). But if i don't think you can ground that shielding to make it more effective, as it would then likely lower the total power efficiency of the system and screw up the field.

So i think it might be harder to do than it first looks. But it's definitely a cool effect, and worth testing

What might be interesting to also try sometime, is to Magnetically Couple a magnet rotor to the moving magnets (mount a flat horizontal disk with mags embedded around it directly above the rolling mags' circular "race track", with the rotor's rotating center shaft vertical); so the rolling mags spin the disk a short distance away in repulsion mode (...if you could somehow get the rolling mags to always line up in the same polar orientation facing "up", and keep them from attaching to the Rotor, lol). 

It's even possible that this motion caused by Magnetic Coupling would be "Low CEMF" or even "CEMF Free"... In that the current won't rise in the degaussing coil as much as "normal" operation of a motor, when the mechanical load / drag seen at the magnetically coupled disk increases (...although this certainly needs to be tested, lol).
