A magnetic field sensor for measuring an external magnetic field, including a sensor unit; and a flux conductor assembly including at least one switchable element, which is designed to deflect a flux of the external magnetic field onto the sensor unit as a function of a switching state of the at least one switchable element, the sensor unit being designed to measure the deflected flux of the external magnetic field; and an evaluation unit, which is designed to ascertain a value of the external magnetic field as a function of the deflected flux of the external magnetic field measured by the sensor unit and the switching state of the at least one switchable element.

Magnetic field sensor and method for measuring an external magnetic field

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.

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

A magnetic sensor device having a first magnetic core structure which is aligned along a first central longitudinal axis and has at least one first coil, and having a second magnetic core structure which includes at least one second coil, the second magnetic core structure extending from a first end face of the second magnetic core structure along a second central longitudinal axis to a second end face of the second magnetic core structure, the second central longitudinal axis lying in a plane aligned in a direction normal to the first central longitudinal axis, and the second magnetic core structure being positioned in relation to the first magnetic core structure in such a way that a clearance between the first end face of the second magnetic core structure and a first center of mass of the first magnetic core structure is less than 20% of a maximum extension of the first magnetic core structure along the first central longitudinal axis.

Magnetic sensor device and manufacturing method for a magnetic sensor device

A magnetic field sensor device and a corresponding production method are described. The magnetic field sensor device includes a substrate, which has a trench, a ferromagnetic nanowire formed in the trench, a first electrical connection for the electrical connection of a first end of the ferromagnetic nanowire, a second electrical connection for the electrical connection of a second end of the ferromagnetic nanowire, and a magnetic field detection device for detecting a magnetic field in the region of the nanowire.
