Abstract

The invention relates to a system for measuring a magnetic field (12) that includes a magnetic sensor (2) characterized in that the system has a signal for electrical measurement on the basis of the paired field (12) being measured and an electronic device (2) for suppressing sensor shift, and is further characterized in that the shift suppression device includes a symmetrical AC biasing means (20) for the symmetrical AC bias of the sensor (2) to a predetermined bias frequency.
