I read about electrons and positrons free fall within a superconducting cylinder, in this book (p 105):
https://www.amazon.com/dp/0521675537/?tag=pfamazon01-20
I don't understand what I read.
Apparently, electrons would feel an electric field mg/e that would actually freeze them in the cyclinder. This is already not totally clear. But I assume that any motion would create huge reacting currents in the cylinder to balance the motion. This would be the usual Lenz law. But I would like to that understand better.
Where I really don't understand is when positrons are discussed.
Apparently they would feel a -mg/e field that would in total result in a 2g acceleration. I feel this is very strange since this is contradictory to my usual understanding of the Lenz law: the induced current would then re-inforced the motion instead of damping it.
Any suggestion ?
Thanks
