Abstract
PURPOSE:To perform magnetic detection with superior temperature characteristics by winding an exciting coil and a sensor coil around amorphous magnetic alloy and detecting the rising time and falling time of a voltage induced across the sensor coil. CONSTITUTION:A high frequency current is supplied from a high frequency current source to the exciting coil 2 wound around a magnetic core 1 made of amorphous magnetic alloy and when an external magnetic field Hex operates on the magnetic core 1, the voltage (e) is induced across the sensor coil 3. Differentiating circuits 11 and 12 generates a voltage obtained by differentiating the induced voltage (e) across a resistance 12 to which the input terminal of a comparator 12 is connected. The phase difference between the maximum point and minimum point of the induced voltage or time t1 is detected by the sensor 3 to detect the polarity and intensity of the external magnetic field Hex continuously.
