One embodiment of the present invention relates to a magnetic field sensor comprising a squat soft-magnetic body disposed on a surface of a substrate comprising a magnetic sensor array having a plurality of spatially diverse magnetic sensor elements disposed in a predetermined configuration. In the presence of an external magnetic field the squat soft-magnetic body becomes magnetized to generate a reactionary magnetic field. The plurality of magnetic sensor elements are respectively configured to measure a magnetic field value of a superposition of the external magnetic field and the reactionary magnetic field along a first axis (e.g., a z-axis), resulting in a plurality of spatially diverse measurements of the magnetic field component along the first axis. The plurality of spatially diverse measurements may be used to compute magnetic field components of the external magnetic field along a plurality of axes (e.g., x-axis, y-axis, and z-axis).
