Magnetic braking of magnets sliding along a sloped aluminum surface

[RunningBare]

Keep in mind you have to consider the area/volume of the metals, I would doubt very much that a small piece glued to the magnet would have any effect.

Just a weird thought:

Attach an aluminum disc to the bottom of the magnet and slide it down the aluminum ramp.

The aluminum disc will remain static WRT the magnet. The magnet will induce Foucault (eddy) currents and an oppositional magnetic field in the ramp. The moving oppositional field in the ramp will induce secondary eddies and more oppositional magnetic forces into the aluminum disc.

... or maybe not.

It is my opinion that the magnets flip over, instead of sliding down, because the south side of the magnet is attracted to the alum more. It cant get a good grip and tumbles the rest of the way.

May be more going on its hard to tell. The north side seems to attract to the alum only very little.

There appears to be either a difference in the north and south magnet fields, or different elements constructs create different magnet field interaction, or both.

0c one of them things in the whipmag no one seem to have observed is the use of inductors that seems (with what I had to measure with ) no major reaction to the slowing of the moving rotor. Just one of them observations. Hmm,,,,
I see a copper plate in the times to come for me.

CLaNZeR, IIRC actually did do rundown comparisons with the MKJDs of several different materials (different alum. alloys, I think) and found that they do slow the AGW rotating stator enough to stabilize it, and the different alloys behave slightly differently in this regard. I don't know if that's significant at all but I thot I'd mention it.

TK I saw some of that. yet in my not so accurate rundown times, I saw no real variation of the rotor with only them MKJD.  Were as I can account for the induction action of such (rotor magnet layout, I expected more drag). I could not measure such.
Any practical application of such, Hmm who knows. May try a coil, or coils and drive the rotor and see what happens.
