 Once these difficulties have been handled, it is indeed possible to consider electromagnetism in the Aharonov-Bohm effect as faithfully represented at a time by a set of intrinsic properties of loops in space (or more generally space-time). But if one does so, then electromagnetism itself manifests (strong)  nonseparability.  For these intrinsic properties do not supervene on any assignment of qualitative intrinsic physical properties at spacetime points in the region concerned, nor even in arbitrarily small neighborhoods of those points. Whether the magnetic field remains constant or changes, the associated electromagnetism constitutes a nonseparable process, and so the Aharonov-Bohm effect violates  spatiotemporal separability.  If the motion of the particles through the apparatus is a nonseparable process, then it is possible to account for the \(AB\) effect in terms of a purely local interaction between electromagnetism and this process. For the particles effectively traverse loops traced out by closed curves C on their nonlocalized “trajectories”, and so they interact with electromagnetism precisely where this is defined.
