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

Trapped electrons traveling in circular loops at extreme speeds inside graphene quantum dots are highly sensitive to external magnetic fields and could be used as novel magnetic field sensors with ...

Physicists have unveiled a breakthrough in quantum sensing by demonstrating a 2D material as a versatile platform for next-generation nanoscale vectorial magnetometry. A team of physicists at the ...

Researchers built a fingernail-sized magnetometer using metasurfaces that measures fields billions of times weaker than Earth's, opening new paths for quantum sensing. At the heart of the sensor is an ...

Monarch butterflies may hold the key to one of biology's biggest unsolved puzzles: how animals tap into Earth's magnetic ...

A guide for engineers balancing performance, reliability, and manufacturability across today’s smart systems By Barry Brents, ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

Unlike conventional Hall sensors that only respond to the field component perpendicular to the device surface, the Type CSA-1 single-axis and the Type 2SA-1 two-axis sensors respond to a magnetic ...

Why there’s a need to assess current-flow distribution. How an arrangement was made for the measurement using a controlled magnetic field, laser-induced current flow, and a subtle physics-materials ...
