  • Patent number: 11555870
    Abstract: A magnetic sensor device includes a magnetic sensor detecting a detection-target magnetic field, and a soft magnetic structure near the sensor. In an orthogonal coordinate system having two orthogonal axes for representing an applied field strength and a magnetization-corresponding value, coordinates representing the applied field strength and the magnetization-corresponding value move along a minor loop not in contact with a major loop as the strength of an external magnetic field including the detection-target magnetic field varies within a variable range, where the applied field strength is a strength of a magnetic field applied to the soft magnetic structure, the magnetization-corresponding value is a value corresponding to magnetization of the soft magnetic structure, and the major loop is, among loops traced by a path of the coordinates as the applied field strength is varied, a loop that is the largest in terms of area of the region enclosed by the loop.
