Hall effect Hall effect Edwin Herbert Hall ( November 7, 1855 - November 20, 1938) was an American physicist who discovered the " Hall effect". Hall conducted thermoelectric research at Harvard and where he also wrote numerous physics textbooks and laboratory manuals. ...more on Wikipedia about "Edwin Hall"
The Hall effect refers to the potential difference (Hall voltage) on opposite sides of a thin sheet of conducting or semiconducting material in the form of a 'Hall bar' or a van der Pauw element through which an electric current is flowing, created by a magnetic field applied perpendicular to the Hall element. The ratio of the voltage created to the amount of current is known as the Hall resistance, and is a characteristic of the material in the element. Dr. Edwin Hall discovered this effect in 1879. ...more on Wikipedia about "Hall effect"
A Hall effect sensor is an electronic device that varies its output voltage in response to changes in magnetic field density. Hall sensors are used for proximity switching, positioning, speed detection and current sensing applications. ...more on Wikipedia about "Hall effect sensor"
A Hall effect thruster is a type of ion thruster in which the propellant is accelerated by an electric field in a plasma discharge with a radial magnetic field. Also known simply as plasma thrusters, HETs use the Hall effect to trap electrons and then use the electrons to ionize propellant, efficiently accelerate the ions to produce thrust, and neutralize the ions in the plume. ...more on Wikipedia about "Hall effect thruster"
The quantum Hall effect is a quantum-mechanical version of the Hall effect, observed in two-dimensional systems of electrons subjected to low temperatures and strong magnetic fields, in which the Hall conductance σ takes on the quantized values ...more on Wikipedia about "Quantum Hall effect"
The Thermal hall effect is the thermal analog of the Hall effect for conductors. In particular, the Righi-Leduc Effect describes the heat flow resulting from a perpendicular temperature gradient and vice versa, and the Maggi-Righi-Leduc effect descrbies changes in thermal conductivity when placing a conductor in a magnetic field. ...more on Wikipedia about "Thermal Hall effect"
