Hall effect

noun

, Physics, Electricity.

1. the electromotive force generated in a strip of metal longitudinally conducting an electric current and subjected to a magnetic field normal to its major surface.

Hall effect

noun

1. the production of a potential difference across a conductor carrying an electric current when a magnetic field is applied in a direction perpendicular to that of the current flow

Hall effect

/ hôl /

1. A phenomenon that occurs when an electric current moving through a conductor is exposed to an external magnetic field applied at a right angle, in which an electric potential develops in the conductor at a right angle to both the direction of current and the magnetic field. The Hall effect is a direct result of Lorentz forces acting on the charges in the current, and is named after physicist Edwin Herbert Hall (1855–1938).
