- Abstract: An experiment to observe the Aharonov-Bohm effect is discussed. A solenoid
which consists of a large number of point magnetic dipoles is considered as the
source of a vector potential, which acts on a charged particle, and such
potential has an electromagnetic field of zero strength in the region of a
nonzero vector potential. A detailed microscopic analysis of the change in the
quantum state phase of the entire system, namely, a particle and a set of
dipoles, reveals the origin of the apparent nonlocality of the action of the
vector potential, and shows the locality of the phase change mechanism. An
analysis of an experiment with a solenoid shielded by a superconducting shell
is given.

We propose an electrodynamic Aharonov-Bohm scheme where a nonzero AB phase difference appears even if the interferometer paths do not enclose a magnetic flux.
In the proposal, the current in a solenoid outside the interferometer varies in time while the quantum particle is in a superposition state inside two Faraday cages.

The Aharonov-Bohm (AB) phase that makes its entry in the above bizarre effect is also deployed to derive the observed magnetic flux quantisation in superconductors.
The Dirac result implies that the existence of a single magnetic monopole anywhere in the universe would entail quantisation of the product of a particle's electric charge and the monopole's magnetic charge.
