DC Magnetic Field Sensor Based on Matteucci Effect

Tomasz Charubin , Michał Nowicki , Roman Szewczyk


In this paper a measurement device for measuring DC axial magnetic field is described. The device uses Matteucci Effect in its working principle. There are three main components of this extremely simple sensor – magnetic amorphous nanowire, driving coil and timer-counter. The output signal is time-based, as the time between negative and positive ME voltage peaks changes proportionally to applied DC magnetic field, when the core is magnetized by known larger AC magnetic field. The obtained characteristic is almost linear, which makes the ME magnetic field sensor signal suitable for further processing. Moreover, time-based output allow for high resolution and direct digitalization of the measurement results.
