ABSTRACT:
A fluxgate sensor integrated in a printed circuit board. The fluxgate sensor has soft magnetic cores having a lower core and an upper core mounted on the lower core, for forming a closed magnetic path on a printed circuit board, an excitation coil formed as a metal film, alternately winding the upper and the lower soft magnetic cores substantially in a number ‘8’ pattern, and a pick-up coil formed as a metal film, having a structure of winding the upper and the lower soft magnetic cores substantially in a solenoid pattern, the pick-up coil being placed on the same plane as an external contour of the excitation coil.
