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 ...

Seeed Studio sent us a review sample of the XIAO Soil Moisture Sensor powered by the XIAO ESP32C6 wireless module and running ...

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 ...

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 ...

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 ...

If you read about Hall effect sensors — the usual way to detect and measure magnetic fields these days — it sounds ...
