The Hall effect sensor monitors the field of the permanent magnet and uses that information to modulate the magnetic field of the electromagnet, with everything being crunched by the Arduino.

It’s something [mircemk] demonstrates, with an Arduino-powered magnetic field strength meter that uses a UGN 3503U Hall effect device. The circuit is extremely simple, comprising the sensor, an ...

Using the anomalous Hall effect (AHE), researchers devised an extremely sensitive magnetic-field sensor with low noise.

Researchers have invented Hall effect magnetic field sensors that are operable at high temperatures and harmful radiation conditions. The sensors will find applications in space craft and nuclear ...

Texas Instruments is claiming “industry’s most accurate 3D Hall-effect position sensor” for one that provides 2.6% full-scale total error at room temperature.

The first device in a family of 3D Hall-effect position sensors, TMAG5170 is intended for factory automation and motor-drives. Designed for rotational sensing (diagram below), it has three independent ...

In-plane magnetic fields are responsible for inducing anomalous Hall effect in certain films, report researchers. By studying how these fields change electronic structures, the team discovered a ...

In-plane magnetic fields are responsible for inducing anomalous Hall effect in EuCd2Sb2 films, report researchers from the Institute of Science Tokyo. By studying how these fields change ...
