Hall effect in Science
Hall effect
  (hôl)   
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).
