Abstract

PURPOSE: To enable to obtain a high-precision results by measuring the direction of each magnetometer for the orthogonal axes of coordinates to seek for the magnetic field through operation using said measured result.
CONSTITUTION: More than three, for example three pieces of fluxmeters Fx, Fy, Fz are so fixed that each detection axis may be at an optional angle and each fluxmeter may be in a cubic arrangement. Each fluxmeter output is amplified through the amplifiers 2x, 2y, 2z, multiplied by aWf through the coefficient multiplyers XaWXf, after being added by a adders 3y, 3z is squared by the square circuits 4xW 4z. After being added by the adder 5 said output is put in the extraction circuit 6. The output of the extraction circuit gives the intensity of magnetic field searched for.
