Quantum Falling Magnet: Lenz's Law Demo?

I take it that it would be ok that in the classic demonstration of Lenz's law with the falling magnet, to replace the magnet with some quantum particle of non-zero magnetic moment and make the tubing a solenoid in order to generate a current as the particle fell? Obviously the current would be miniscule, given the small moment and particle size; I'm just making sure that I have the general idea right first.

p.s. Would this be the right sub-forum for this? Or would it belong in the particle or even classical physics section?

Yes, Experiments are in progress to detect Magnetic Monopoles using this method. It probably won't be a viable method to detect say the the Spin of a neutron.
 
Are you talking about arrangements using SQUIDs like Cabrera did in '82?
 
Yes, That is the one
 
I'm a little fuzzy as to whether the particles lose any kinetic energy when passing through the SQUID there.

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
