I'm just curious, in the Coulomb gauge changes made locally to the scalar and vector potential fields are propagated instantaneously, classically we wave off this problem since the potentials aren't directly observable... except they are in Aharanov-Bohm. Presumably there's something that saves causality but what is it? If I pass two particles either way around an enclosed magnetic field, why can't changes in this magnetic field be instantaneously recognized in the interference pattern when the two particles are recombined?
