Solution . T HE A HARONOV-B OHM EFFECT it is exactly these questions that make the Aharonov-Bohm effect. The Aharonov–Bohm effect, sometimes called the Ehrenberg–Siday–Aharonov–Bohm effect, is a quantum mechanical phenomenon in which an electrically charged particle is affected by an electromagnetic potential (φ, A), despite being confined to a region in which both the magnetic field B and electric field E are zero.

In books it's infinite solenoid most of the time, which makes some regions of space not simply connected. What intrigues me is the fact that in real experiment we can't use infinite solenoid.

Now Michael Hohensee of the University of California, Berkeley, and his colleagues, have an idea for the gravitational equivalent of this experiment. Aharonov-Bohm effect: lt;p|>||||| The |Aharonov–Bohm effect|, sometimes called the |Ehrenberg–Siday–Aharonov–Bohm| effe World Heritage Encyclopedia, the In 1959, Yakir Aharonov and David Bohm stated that a potential was itself a fundamental physical entity, and would affect a charged particle even in a region in which there was no magnetic field, and therefore no force acting on the charged particle. They proposed the following experiment to verify the existence of the effect.
