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

Fluxgate magnetometers represent a cornerstone technology in magnetic field measurements, utilising a ferromagnetic core excited by an alternating current to gauge weak, quasi‐stationary magnetic ...

Fluxgate current sensors have emerged as a robust technology for the measurement of both alternating and direct currents, harnessing the non-linear magnetic characteristics of ferromagnetic materials.
