The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and a magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879.  Hall Effect. If an electric current flows through a conductor in a magnetic field, the magnetic field exerts a transverse force on the moving charge carriers which tends to push them to one side of the conductor. This is most evident in a thin flat conductor as illustrated. A buildup of charge at the sides of the conductors will balance this magnetic influence, producing a measurable voltage between the two sides of the conductor. The presence of this measurable transverse voltage is called the Hall effect after E. H. Hall who discovered it in 1879. Hall Voltage for Positive Charge Carriers. The transverse voltage (Hall effect) measured in a Hall probe has its origin in the magnetic force on a moving charge carrier. The magnetic force is where is the drift velocity of the charge. A buildup of charge at the sides of the conductors will balance this magnetic influence, producing a measurable voltage between the two sides of the conductor. The presence of this measurable transverse voltage is called the Hall effect after E. H. Hall who discovered it in 1879. Hall effect. An effect whereby a conductor carrying an electric current perpendicular to an applied magnetic field develops a voltage gradient which is transverse to both the current and the magnetic field. It was discovered by E. H. Hall in 1879. The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and a magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879. Hall effect in semiconductors [edit]. When a current-carrying semiconductor is kept in a magnetic field, the charge carriers of the semiconductor experience a force in a direction perpendicular to both the magnetic field and the current. At equilibrium, a voltage appears at the semiconductor edges. Hall effect. n. 1. (General Physics) 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. [named after Edwin Herbert Hall (1855-1938), American physicist who discovered it].  A Hall effect sensor is a transducer that varies its output voltage in response to a magnetic field. Hall effect sensors are used for proximity switching, positioning, speed detection, and current sensing applications.  (172). It is clear that the Hall voltage is proportional to the current flowing through the ribbon, and the magnetic field-strength, and is inversely proportional to the number density of mobile charges in the ribbon, and the thickness of the ribbon. In fact, this property of the Hall voltage is exploited in instruments, called Hall probes, which are used to measure magnetic field-strength. Suppose that the thickness of the conducting ribbon is, and that it contains mobile charge carriers per unit volume. Note that the Hall voltage is directly proportional to the magnitude of the magnetic field.
