Hall effect

noun Physics

The production of a potential difference across an electrical conductor when a magnetic field is applied in a direction perpendicular to that of the flow of current.The resistivity, which is the inverse of the conductance, in the Hall effect varies linearly with the applied magnetic field....

There's also the fractional quantum Hall effect: electrons trapped between two semiconductor surfaces can appear as quasi-particles with charges less than those of single electrons.
In a normal Hall effect, a voltage is created perpendicular to an electric current as it flows through a conductor in a magnetic field.

Origin

Early 20th century: named after Edwin H. Hall (1855–1938), American physicist.
