So happy to hear this. I've been hoping for some sort of breakthrough ever since I first encountered footage of magnets falling through Cu tubes at an extremely leisurely pace.


If you haven't seen it, levitating frogs are also quite wonderful. https://slate.com/business/2014/05/nobel-prize-in-physics-an...

An Ig Nobel AND a Nobel. That's quite the achievement.


That article was a great story! Thanks for sharing.


Any conductive material for the tube will have a similar effect. It isn't specific to copper.

The moving magnet induces a current in the tube which in turn creates the magnetic field that interacts with the magnet.


Not any conductive material, obviously won’t work won’t work, nor magnetic steel / stainless steel alloys.


I meant: obviously iron won’t work.


Could you elaborate why iron pipes wouldn't work?


The magnet would try to stick to the side of the pipe through "normal" magnetism.


I see, thanks!


Eddy currents


“Eddies,” said Ford, “in the space-time continuum.”

“Ah,” nodded Arthur, “is he? Is he?”
