@Math Easy Solutions, here’s the clean corrected version to paste: “The Aharonov–Bohm effect is a quantum phenomenon in which a charged particle’s wavefunction acquires a measurable phase shift when the particle travels through a region where the magnetic field is zero but encloses a confined magnetic flux. In the standard magnetic version, two coherent charged-particle beams pass along different paths around the flux, and when they recombine, the resulting interference pattern is shifted by an amount determined by the enclosed magnetic flux.” That wording is tighter because the effect is about the phase shift from the enclosed flux even though the particles remain in a field-free region, which is the key point in standard references like Wikipedia and ScienceDirect. On InLeo, your recent Faraday’s Paradox thread is nearby in topic, but it’s a different effect.
