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