On 21 June, the Chinese Academy of Sciences hailed a breakthrough – a major upgrade to a kind of quantum device that measures magnetic fields. Magnetometers have been used to detect submarines since ...

This report shows the results of a test survey aimed at comparing four different UAV-based (Unmanned Aerial Vehicle) magnetometers and their capabilities to detect various infrastructure utilities.… ...

At the heart of the magnetometer are rubidium atoms and their reaction to a magnetic field. If rubidium atoms are stimulated by a laser light, the frequency of the laser light changes.

An innovative magnetometer that can replace conventional technology in applications such as neuroimaging, mineral exploration and molecular diagnostics has been developed by scientists. Its ...

A highly sensitive diamond quantum magnetometer utilizing nitrogen-vacancy centers can achieve millimeter-scale resolution magnetoencephalography (MEG). The novel magnetometer, based on continuous ...

A WWII submarine-hunting device helped prove the theory of plate tectonics With a boost from World War II, the fluxgate magnetometer became a portable and invaluable tool ...
