Hall sensors may be utilized for contactless measurements of direct current in current transformers. In such a case the Hall sensor is mounted in a gap in the magnetic core around the current conductor. [24] As a result, the DC magnetic flux can be measured, and the DC in the conductor can be calculated.
A Hall effect sensor uses the Hall effect to measure the magnitude of a magnetic field. Other languages Čeština: Animace funkce Hallovy sondy využívající Hallova jevu k měření intenzity magnetického pole .

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 ...
In ferromagnetic materials (and paramagnetic materials in a magnetic field), the Hall resistivity includes an additional contribution, known as the anomalous Hall effect (or the extraordinary Hall effect), which depends directly on the magnetization of the material, and is often much larger than the ordinary Hall effect.
6 kW Hall thruster in operation at the NASA Jet Propulsion Laboratory. 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.
For diodes or integrated circuits with two connections (e.g. temperature sensors) the middle lead is either not connected or omitted entirely. Comparison between the E-Line/Miniplast package and the TO-92 package. In the late 1960s, Ferranti introduced a smaller package with a compatible footprint, called "E-Line".
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
