Aharonov-Bohm effect

noun
Aha·ro·nov-Bohm effect | \ ˌä-hä-ˈrō-ˌnȯv-ˈbōm- \

Definition of Aharonov-Bohm effect 

physics

: the correlation between the interference (see interference sense 3) pattern of a beam of electrons that has been split and subsequently recombined and a magnetic field that the beams bypassed while separated

Note: A beam of electrons can be separated and sent on two paths around the outside of an area that contains a magnetic field. The paths are recombined after passing the magnetic field. The recombined beam will display an interference pattern (from the interaction of the two paths) that is linked to the nature of the magnetic field that the paths went past, even though they did not pass directly through it. The relationship between the interference pattern and the magnetic field is called the Aharonov-Bohm effect.
