Quantum physics: The human body is controlled by electrical impulses in, for example, the brain, the heart and nervous system. These electrical signals create tiny magnetic fields, which doctors could ...

A team of physicists at the University of Cambridge has unveiled a breakthrough in quantum sensing by demonstrating the use of spin defects in hexagonal boron nitride (hBN) as powerful, ...

Scientists at the University of Birmingham have developed a new sensor to measure weak magnetic signals in the brain, which has the potential to increase understanding of connectivity in the brain, ...

The Debye effect could be used hunt submarines using the magnetic signatures of their wakes. Seawater is salty, full of ions of sodium and chlorine. Because those ions have different masses, any nudge ...

New MFxM magnetic proximity switches detect magnetic fields over large distances up to 60 mm. These sensors can be used effectively in applications where the target is located behind a wall of ...

A new type of sensor that levitates dozens of glass microparticles could revolutionize the accuracy and efficiency of sensing ...

Getting a magnetic field to balance on another magnetic field is about as easy as balancing a bowling ball on the tip of an ink pen. With a little help from an Arduino mega, however, [EmmaSong] was ...

The human body is controlled by electrical impulses in the brain, the heart and nervous system. These electrical signals create tiny magnetic fields, which doctors could use to diagnose various ...

Researchers have designed a new Optically Pumped Magnetometer (OPM) sensor for magnetoencephalography (MEG). The sensor is smaller and more robust in detecting magnetic brain signals and ...
