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.… ...

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 ...

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.

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

Adafruit have announced the availability of its new Triple-axis Magnetometer offering a sensor capable of sensing ranges from +-50 gauss (+- 5000 uTesla!) with no range-setting required. For high ...

"Nevertheless, our development shows that this magnetometer is also promising for planetary probes with two laser beams—provided the magnetic field is not too weak.
