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

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 ...

This report shows the results of a test survey aimed at collecting reference data using four different UAV-based (Unmanned Aerial Vehicle) magnetometers against UXO (Unexploded Ordnance) surrogate ...

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 ...

Imperial College London researchers are celebrating a huge milestone after their magnetometer instrument successfully ...

Magnetic fields are everywhere, from the human body to the metal in a buried land mine. Even molecules such as proteins generate their own distinctive magnetic fields. Both magnetic resonance imaging ...

Important instruments for neuroscience and medical diagnostics, optically pumped magnetometers measure responses of polarized atoms to produce information about the low-frequency external field. They ...

A groundbreaking fiber-coupled diamond magnetometer has been possible by Element Six’s high purity CVD diamond and is set to advance structural material aging and medical diagnostics. A group of ...

An emerging generation of quantum sensors are capable of performing tasks such as detecting the magnetic fields of thoughts with unprecedented levels of sensitivity. Now, the European Space Agency ...

The Venus flytrap (Dionaea muscipula) is a carnivorous plant that encloses its prey using modified leaves as a trap. During this process, electrical signals known as action potentials trigger the ...
