Definition of Hall effect in English:

Hall effect


  • 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.

    • ‘In a normal Hall effect, a voltage is created perpendicular to an electric current as it flows through a conductor in a magnetic field.’
    • ‘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.’
    • ‘While lasers were being fabricated for optical communications, basic research in III-V semiconductors led to the discovery of the fractional quantum Hall effect by Horst Störmer and Daniel Tsui.’
    • ‘The work has been made possible through the Caltech team's earlier discovery of a phenomenon dubbed the ‘giant planar Hall effect.’’


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