Abstract:
1. A magnetic field sensor, comprising: a plurality of spatially diverse magnetic sensor elements disposed in a predetermined configuration comprised within or on a surface of a substrate, wherein the plurality of magnetic sensor elements are configured to measure a superimposed magnetic field values, of a superposition of an external magnetic field and a reactionary magnetic field, along a first axis; a squat soft-magnetic body attached directly or via interstitial structures or layers to the substrate, wherein the entire squat soft-magnetic body comprises a spherical shaped soft-magnetic body, and wherein in the presence of the external magnetic field the squat soft-magnetic body is configured to generate the reactionary magnetic field in a manner that causes the superimposed magnetic field to have different magnetic field values along the first axis at the plurality of spatially diverse magnetic sensor elements, which collectively indicate magnetic field components along a plurality of axes; and a measurement unit configured to compute magnetic field components along the plurality of axes based upon the measured magnetic field values of the superposition of the external magnetic field and the reactionary magnetic field along the first axis.
