A Hall effect sensor (also known as a Hall sensor or Hall probe) is any sensor incorporating one or more Hall elements, each of which produces a voltage proportional to one axial component of the magnetic field vector B using the Hall effect (named for physicist Edwin Hall). Hall sensors are used for proximity sensing, positioning, speed ...
The term ordinary Hall effect can be used to distinguish the effect described in the introduction from a related effect which occurs across a void or hole in a semiconductor or metal plate when current is injected via contacts that lie on the boundary or edge of the void. The charge then flows outside the void, within the metal or semiconductor ...
A hall-effect magnetic field sensor is then used to measure the induced current with its output being directly proportional to the magnitude of the current flowing. In the simplest configuration, a hall-effect magnetic field sensor can be placed adjacent to the conductor and its output measured but there are limitations.
Hall-effect thruster. In spacecraft propulsion, a Hall-effect thruster (HET) is a type of ion thruster in which the propellant is accelerated by an electric field. Hall-effect thrusters (based on the discovery by Edwin Hall) are sometimes referred to as Hall thrusters or Hall-current thrusters. Hall-effect thrusters use a magnetic field to ...
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. In 1880, Hall's experimentation was published as a doctoral thesis in the American Journal of Science and in the Philosophical Magazine. Hall effect sensors use his Hall effect to
The planar Hall sensor is a type of magnetic sensor based on the planar Hall effect of ferromagnetic materials. [1] [2] It measures the change in anisotropic magnetoresistance caused by an external magnetic field in the Hall geometry. As opposed to an ordinary Hall sensor, which measures field components perpendicular to the sensor plane, the ...
