SENSOR APPARATUS PRODUCTION METHOD FOR A SENSOR APPARATUS HAVING AT LEAST ONE MAGNETIC CORE AND METHOD FOR DETERMINING A FIELD STRENGTH OF A MAGNETIC FIELD IN AT LEAST ONE SPATIAL DIRECTION

摘要

The present invention relates to a sensor device having at least one magnetic core (10) disposed on one or more carrier surfaces (16), said magnetic core comprising at least one soft magnetic material (12) Each of the magnetic cores 10 may be defined with one central longitudinal plane 18 oriented perpendicularly to the magnetic core 10 and dividing each magnetic core 10 into two halves having the same mass, One or more coils are arranged around one or more magnetic cores and / or adjacent to one or more magnetic cores, and one or more magnetic cores 10, on the inside thereof, increase the drive energy to be provided for expansion of the magnetic domain wall, And has sections that can be used to locally control the start of magnetization inversion of the magnetic core 10 of the magnetic core 10 as desired. The present invention also relates to a method of manufacturing a sensor device having at least one magnetic core (10). The present invention also relates to a method for determining the magnetic field strength of a magnetic field in at least one spatial direction.
