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 ...

Microsystems, a leading manufacturer of magnetic sensing and power integrated circuits, finds itself at a crucial juncture as it navigates through a challenging automotive semiconductor market. The ...

Your own brain also emits tiny pulses of magnetic energy every time a neuron fires. But measuring what direction those fields are pointing, for precise atomic sensors in particular, can get tricky.

The actively controlled levitation base uses a magnetic sensor to detect the changing field as the snail moves ... This is picked up by a circuit in the snail, and used to power the LEDs inside.

A pair of physicists at the University of Crete has found that some types of biological magnetoreceptors used by various creatures to navigate, operate at or near the quantum limit. In their paper ...

Japanese researchers have developed the world’s first superconducting flux qubit that functions in a zero magnetic ... the ...
