    摘要: A magnetic compensating circuit includes a magnetic sensor (1), a control circuit (2) for generating a signal for magnetic compensation, and coils (3) for magnetic compensation. The magnetic sensor has a pair of amorphous magnetic substance wires (101) arranged in parallel, coils (102) for providing the pair of amorphous magnetic substance wires with bias magnetic fields in directions opposite to each other, a high-frequency power source (105) for supplying the pair of amorphous magnetic substance wires with high-frequency currents, and circuits (106, 107, 108, 109) for outputting a potential difference derived from the output of the pair of amorphous magnetic substance wires. Thus, this magnetic compensating circuit is capable of detecting a minute external magnetic field with high accuracy.
