It’s something [mircemk] demonstrates, with an Arduino-powered magnetic field strength meter ... has a known relationship to the gauss level the sensor is experiencing, so while the accuracy ...

Abstract: In compact power electronic devices, magnetic-ring-free current sensors are increasingly preferred due to their compact size and lightweight nature. However, in high-precision small current ...

Here, we developed a novel optical fiber weak magnetic sensor based on bismuth-doped silica optical fibers (BDSF). Theoretical analysis indicates that the energy level splitting of Bi 2p orbital spin ...
