I am curious to see the results. Most things respond to electric and magnetic fields in one way or another. It will be interesting to see the effects, or lack thereof. for trying!
One note I would like to make is with respect to the uncertainty principle; it comes from years of exasperation over misapplication. One of the areas I studied was social sciences and I have seen wildly inaccurate interpretations of this very simple and specific idea.
It is very commonly misapplied. The principle is a basic concept in quantum physics and sets a limit of precision of two physical properties of sunatomic phenomena that are conjugate - such as position and momentum.
It does not apply to relationships between properties that are not complimentary. It does not apply to systems that do not have a matter wave nature. It cannot be extrapolated over other systems.
Perhaps number one principle that Heisenberg's gets confused with is called observer effect. That one states that by observing a state we change it.
I think of your experiment as a black box: we know the inputs and we will know the results, whatever happens in the middle, the mechanism by which the change may occur, should it occur, will warrant discussion at that time.
For now, I am looking forward to the results, however small the sample size.
