Definition of HALL EFFECT
: a potential difference observed between the edges of a conducting strip carrying a longitudinal current when placed in a magnetic field perpendicular to the plane of the strip
Origin of HALL EFFECT
Edwin H. Hall †1938 American physicist
First Known Use: circa 1889
Development of a transverse electric field in a solid material carrying an electric current and placed in a magnetic field perpendicular to the current. Discovered in 1879 by Edwin H. Hall (1855–1938), the Hall field results from the force exerted by the magnetic field on the moving particles of the current. The Hall effect can be used to measure certain properties of current carriers as well as to detect the presence of a current on a magnetic field.
