  • Multi-axis fluxgate magnetic sensor
    Patent number: 8669763
    Abstract: A ring-shaped first ring-shaped magnetic core, a first excitation coil wound on the first ring-shaped magnetic core, two detection coils wound on the first ring-shaped magnetic core in such a manner that respective input axes of the detection coils are orthogonal to each other, two signal detection/feedback units that detect outputs of the detection coils and feed output signals back to the detection coils, and a first excitation circuit that supplies an excitation current to the first excitation coil are provided, a second ring-shaped magnetic core, a compensation coil wound on the second ring-shaped magnetic core, and a compensation signal generation unit that generates, from an output of a detection coil, a compensation current to be applied to the compensation coil, are further provided, and the second ring-shaped magnetic core and the compensation coil are disposed in positions and directions so that a compensation magnetic field created by the compensation coil cancels interference between magnetic fiel
