I just assumed it was energy-wells created by inductive repulsion.
Guess not!
Hamdi, if you have ambition, duplicate some of your setups with ALL
CONDUCTORS REMOVED. Or at the very least, use one insulating rubberized
supermagnet for the rotating portion, and any old supermagnet for the
non-rotator. This eliminates the electric currents and the
induction-maglev artifact.
I think "bonded" neo supermagnets are still available, made of neo alloy
powder, mixed in flexible "rubber" polymer, so, non-conductive (but also
there are no one-tesla neo rubber-magnets.)
(No, I DON'T think Hamdi's discovery is just induction. But induction
creates artifacts. So perhaps slap together a quick version which lacks
the rotating conductors. Verify that the phenomenon still appears.)
High-speed rotating conductors, placed near magnets, have energy-wells.
This includes high-speed rotating neo magnets. That one infamous
two-pipes maglev-device on my website is just one of many, many
topologies. E.g., two thick copper strips placed parallel, moving fast in
opposite directions, should stably suspend any supermagnet placed in the
gap between them. Two thick copper disks, touching edges and rotating
opposite, have an energy-well in the "cleft" between them, and will
suspend a small supermagnet cylinder or disk. My favorite is a rotating
copper donut w/wide hole, with a rotating copper disk placed in the hole,
and a significant slot between the two, with the two rotating opposite
(~w/30mph surface speed.) Then, place neo supermagnets in the circular
slot, and adjust the RPMs of the copper parts so the suspended magnet
doesn't move. (I haven't built that one. I didn't have a 500watt DC
motor at the time.)
All these are utterly conventional physics, as far as I know.
But they could produce mysterious artifacts, when in any experiment
involving high-speed rotating supermagnets, where the supermagnets are
made of conductor, rather than of flexible-magnet composite material where
no hundred-ampere induced currents are possible.
(Heh, all these variation appeared in my mind while it was really easy
to think. Not at 5AM in darkness, as is typical. Instead, it was on a
airline flight (Seatac to SF,) with my head bathed in cosmic radiation
which makes a geiger counter roar. All miles-high plane flights expose
us to many millirems. So, try it yourself: always bring a blank
notebook on the flight, and try working on old ideas etc., see if
you make sudden enormous progress with new concepts flooding in. I
always do this, and as a result, invariably solve problems, or get new
insights, harvest "good stuff from the Aether.")
Native American shaman apparently used this trick. But they employed
caves having either massive Radon outgassing, or very "hot" mineral
deposits. Brains bathed in low-level x-rays, such as on airline flights,
will slip into slightly-altered, creative states.)

If the pictures are not enough to interest you, here are numerous
videos of his demonstration of the phenomenon:

If anyone does have any comments or questions, I will be happy to
forward them to Hamdi or put you in touch with him after I get his
permission.
