る磁気飽和を利用した磁気検出装置。 An excitation coil and a magnetic detection coil are arranged in a skewered manner on a bar-shaped magnetic core, and by applying a half-wave rectified pulsating voltage to the excitation coil, the core is excited to a magnetic saturation value, and the magnetic field to be detected is is transmitted through the iron core to cause a magnetic deviation, thereby making it possible to detect the magnetism from a change in the detection output from the detection wire in which the pulsating voltage is induced. Magnetic detection device.
