摘要： A sensor apparatus having at least one magnet core, on at least one carrier surface, which encompasses at least one soft magnetic material and for which a respective longitudinal center plane, which is oriented perpendicularly to the carrier surface and divides the respective magnet core into two halves having an identical mass, is definable, at least one coil being on, around, and/or adjacent to the at least one magnet core, the at least one magnet core having in its interior sub-regions by which an initiation of a magnetization reversal of the respective magnet core is targetedly locally controllable since a drive energy to be applied for propagation of a magnetic domain wall is elevated. Also described is a manufacturing method for a sensor apparatus having at least one magnet core, and a method for ascertaining a field strength of a magnetic field in at least one spatial direction.
