(Nanowerk News) MIT researchers have developed a new, ultrasensitive magnetic-field detector that is 1,000 times more energy-efficient than its predecessors. It could lead to miniaturized, ...

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

BOULDER, Colo.- A tiny sensor that can detect magnetic field changes as small as 70 femtoteslas-equivalent to the brain waves of a person daydreaming-has been demonstrated at the National Institute of ...

Quantum magnetometers are able to detect and visualize the tiniest damage in ferromagnetic materials. In aerospace technology or the automotive industry, they can help to significantly increase the ...

STMicroelectronics has announced a new MEMS-based module that integrates a three-axis magnetometer, a three-axis accelerometer, A/D converters, and control logic on a 2 mm x 2 mm x 1 mm surface mount ...

Physicist have captured a Bose Einstein condensate within a laser beam to made a device that maps magnetic fields more precisely than ever before. The magnetometer relies on the fact that the spins of ...

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 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 ...

Some of the most sensitive methods of measuring magnetic fields use interactions of resonant light with atomic vapour. Recent developments in this vibrant field have led to improvements in sensitivity ...

Back in 1896, a young physicist called Pieter Zeeman was fired for carrying out an experiment against the specific wishes of his laboratory supervisor. Despite the consequences, the experiment led to ...
