Abstract:
A magnetic field sensor includes: a magnetic thin film; a feeder comprising an input and output terminals configured to supply element current to the magnetic thin film; and a detector configured to detect a voltage between ends of the magnetic thin film in a direction perpendicular to a direction of the element current. The magnetic thin film is Rained symmetric about the direction of the element current.
