Abstract

PURPOSE:To let the sensor respond only to the magnitude of signal magnetic fields and eliminate its output fluctuations owing to the rotation of a detecting element within the position signal magnetic fields by applying bias magnetic fields of respectively opposite directions to the ferromagnetic members disposed in the same direction. CONSTITUTION:Magnetroresistance thin film members 3, 4 of ferromagnetic alloy are so disposed as to become of mutually the same bearing, and bias magnetic fields HB, -HB of mutually opposite directions are applied to the respective members. If the magnitudes of the bias magnetic fields and the signal magnetic fields are made constant and their relative angles are changed, the resistances of the members 3, 4 mutually increase or decrease and the output voltage of such magnetic sensor changes more or less, but if the signal magnetic field intensity is smaller than the bias magnetic field intensity, i.e., near the zero point, the output power drift with the change in the magnetic field angle becomes less.
