About aluminum and magnetism, take a magnet and install it on the spin side of the press drill and take aluminum on the bottom, and make spin the drill, you will see that the aluminum will heat even if there is no contact...So there is an effect between aluminum and magnetism some how.
Same thing if you use a ball shape magnet and put it in an aluminum tube you will see some restriction when the magnet ball is drop.

A magnetic resonance imaging (MRI) machine uses an enormous and extremely strong magnet to study a patient's body. The magnet, which has its north pole at the patient's head and its south pole at the patient's feet, is actually a coil of superconducting wire through which electric charges flow.

I slid a magnet down a steeply sloped sheet of aluminum. It slid down
very slowly... it was weird to see for the first time.

Its true, if you drop a magnet through a copper or aluminum pipe or tube or move it just above the surface of an aluminum plate, the magnet will create eddy fields in the aluminum. If the aluminum plate isn't too big you can cause it to flip over with the motion of the magnet, especially if it is a strong magnet like a neo. Incidentally copper is effected the same way aluminum is.

In fact, all diamagnetic materials are affected by Lenzí law. I've experimented with Magnesium and Be, they do the same even though they are lightweight metals. No metals are neutral to magnetism. Even non-metals exhibit a reaction. I've seen frogs suspended by supermagnets, the frogs' life seemed unaffected.

Copper and Al effects with magnets, this is due to Eddy Currents or Eddy Field that sets up
with either a spinning disk or dropping magnet thru copper tube. The Eddy creates a resistance
to gravity and effects or slows down the magnet in a copper tube.

Do you think the present concept with diode at the extremity of collector coil, so it is eddy current who make electron flow, as diode at the extremity block Back EMF, voltage but only few milliamps?

at a very steep angle (50-80 degrees) and let a neo magnet slide
along it downward. You can keep it from slipping off the edge by
tilting the strip left or right as it slides down. Experiencing
that will give you a real sense of just how "real" the interaction
of the rotor and the aluminum must be..
