A magnetometer is a device that measures magnetism: the direction, strength, or relative change of a magnetic field at a given location.
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 ...
High-precision magnetometers are used to measure the strength and direction of magnetic fields for various applications. However, many of today's magnetometers must operate at extremely low ...
