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

The tree diagram shows three perspectives for evaluating the sensitivity limits (green leaves). These perspectives are interconnected (red dashed lines) and are constrained by fundamental principles ...

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 ...

The researchers fabricated chip-based interferometers (pictured) to measure how light propagating through a magneto-optic material changed in response to a magnetic field. WASHINGTON — Researchers ...
