A magnetometer is a device that measures magnetism: the direction, strength, or relative change of a magnetic field at a given location.

If you read about Hall effect sensors — the usual way to detect and measure magnetic fields these days — it sounds deceptively simple. There’s a metal plate with current flowing across it in one ...

Allegro’s ACS37200 200-A Hall current sensor slashes power dissipation with its 50-µΩ shunt, offering 1,400 V of isolation in ...

Scientists at Ames National Laboratory, in collaboration with Indranil Das's group at the Saha Institute of Nuclear Physics (India), have found a surprising electronic feature in transitional ...
