An inspection circuit, which serves as a pseudo circuit of a flux gate-type magnetic element having an excitation coil and a detection coil in a magnetic field detector, for inspecting said magnetic field detection device, which detects a magnetic field from the output of the magnetic element when the intensity of a stationary magnetic field applied to the magnetic element is detected by a time-resolved magnetic equilibrium system. The magnetic field detector is provided with an excitation signal generation unit, a detection signal comparison unit, a feedback signal conversion unit, a feedback signal adjustment unit, a data signal conversion unit, and an excitation signal adjustment unit. The inspection circuit is connected to the output of the excitation signal adjustment unit, and has an alternating signal adjustment unit that inputs an excitation current, which is the output of the excitation signal adjustment unit, as a pseudo signal of a detection signal to an input terminal of the detection signal comparison unit, after the intensity of the excitation current has been adjusted. |
