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

Researchers have developed a precision magnetometer based on a special material that changes optical properties in response to a magnetic field. The device, which is integrated onto a chip, could ...

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 ...

Here’s a fun build from [RootSaid] that is suitable for people just getting started with microcontrollers and robotics — an Arduino-controlled two-wheeled robot. The video assumes you already have one ...

Turning light into magnetic insight The new magnetometer was developed as part of the U.S. National Science Foundation's Quantum Sensing Challenges for Transformational Advances in Quantum Systems ...

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 ...

Abstract: The estimating of the Tolles-Lawson model's coefficients plays an important role in aeromagnetic compensation. The directional cosines, which are indispensable for estimating the ...

Abstract: We report the prototype of a vector magnetometer comprising in-plane tunneling-magnetoresistance (TMR) sensors and a flux chopper. The flux chopper deflects the magnetic flux at 1 kHz, ...
