In the so-called magnetic Aharonov-Bohm effect, a quantum interference pattern shift is produced when electrons move in a magnetic field-free region, thus in absence of forces. Analogous fringe shifts are observed in interference experiments even when electrons travel through a magnetic field and are thus affected by magnetic forces. Because of the vast dedicated literature covering this subject it could require a non trivial effort to attain a comprehensive overview. Therefore, attention has been addressed: i) to recall the theory, ii) to describe the basic aspects of the main experiments realized up today and, iii) to review the long-standing debate regarding the interpretation of the Aharonov-Bohm phase shift as a new quantum topological effect with no analogue in classical theory, or as an energy-related lag effect based on classical forces.

En el fenómeno denominado efecto magnético Aharonov-Bohm, se produce un desplazamiento del patrón de interferencia cuántico cuando los electrones se mueven en una región libre de campo magnético y, por lo tanto, en ausencia de fuerzas. También se observan cambios análogos en experimentos de interfe- rencia cuando los electrones viajan a través de un campo magnético, siendo afectados por fuerzas magnéticas. Debido a la vasta literatura especializada sobre este tema, se requiere un esfuerzo no trivial para abarcar el panorama completo. Así, en este artículo se ha concentrado la atención en los siguientes aspectos: i) rediscutir los fundamentos teóricos, ii) describir los aspectos básicos de los principales experimentos rea- lizados hasta ahora y, iii) revisar el ya largo debate sobre la interpretación del cambio de fase en el efecto Aharonov-Bohm como un fenómeno topológico cuántico sin analogía en la teoría clásica, o como un retardo relativo a la energía causado por la acción de fuerzas clásicas.
