Hall effect

Syllabification: Hall ef·fect

Definition of Hall effect in English:

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.
Example sentences
  • 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.
