Abstract :
In this paper a single axis fluxgate magnetic sensor developed using printed circuit board (PCB) technology is presented. The behavior of the fluxgate device was analyzed with software tools based on the finite element method. The results of the simulations were validated experimentally on fabricated prototypes. The magnetic sensitivity of proposed planar sensing element is about 0.46 mV/μT at 10 kHz and 700 mA current excitation.
