MAGNETIC SENSOR AND MAGNETIC SENSOR SYSTEM

Abstract: a magnetic sensor includes a magnetic field converter, a magnetic field detector, and a plurality of shields aligned in a y direction. the magnetic field converter includes a plurality of yokes. each yoke has a shape elongated in the y direction, and is configured to receive an input magnetic field component in a direction parallel to a z direction and to output an output magnetic field component in a direction parallel to an x direction. the magnetic field detector includes a plurality of trains of elements. each train of elements includes a plurality of mr elements that are aligned in the y direction along one yoke and connected in series. each shield has such a shape that its maximum dimension in the y direction is smaller than its maximum dimension in the x direction.
