FIELD: the invention refers to measuring technique.
SUBSTANCE: the mode of measuring of the increase of the induction of the magnetic field with a three-component differential magnetometer is in that in the orthogonal system of coordinates of the measuring sensor they define its correctional matrix and the matrix of the axles of its windings of compensation of variations, also define in the orthogonal system of coordinates of the compensating sensor its correctional matrix, after installation of the sensors in their places they find the matrix of the orthogonal transformation of coordinates from one orthogonal system of coordinates into another. The readings of the measuring and compensating channels are corrected with the aid of the above-mentioned matrixes defined beforehand.
EFFECT: increases accuracy of the increase of the induction of a magnetic field.
