Less efficient, because more energy will go into heat. Thick is
better than thin, solid is better than tube, and short is better than
long. Aluminum or copper is better than steel most likely.
I've definitely nailed down the effect

I'd say you have demonstrated a necessary condition but not
necessarily
a sufficient condition for the effect.
The effect works with magnetic bearings and not with non-magnetic
bearings. That is sufficient to establish the effect is
electromagnetic. Further, a back-emf is produced, which confirms it
is electromagnetic. How can these facts be if the effect is not
electromagnetic in nature. Heat is totally ruled out as a cause.
