If it does, I think that would be detectable. As the device gets into higher orbits, the magnetic field will get weaker and the force will drop. I'm not sure how much the orbit would have to change to make that apparent though. It might take a very long time.

Another way it might work is by freeing atoms from the backplate of the resonant cavity, like an ion thruster. I hope they include a method of measuring the degradation of the backplate.

I suspect it just won't work, though.
