The types of magnetic sensors that are currently available. How the magnetic sensors work. Applications for the different magnetic sensors. Position sensors enable a variety of functions and controls ...

Chinese scientists have developed an ultra-sensitive, low-noise magnetic sensor capable of detecting extremely weak ...

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 ...

Magnetic fields are everywhere in our solar system. They originate from the sun, planets, and moons, and are carried throughout interplanetary space by solar wind. This is precisely why ...

Because optical encoders are functionally similar, “resolution” is often used as a main characteristic for magnetic encoders, a device providing the angle of a magnet attached to a mechanical shaft ...

Quantum tech is going green. A new take on highly sensitive magnetic field sensors ditches the power-hungry lasers that previous devices have relied on to make their measurements and replaces them ...

An international research team from Germany's Forschungszentrum Jülich and Korea's IBS Center for Quantum Nanoscience (QNS) has developed a quantum sensor capable of detecting minute magnetic fields ...

Quantum devices that measure Earth's magnetic fields could help replace GPS—if researchers can figure out how to tell when such devices are working well, or even at all. A Pentagon contract suggests ...
