Изобретение относится к технике магнитных измерений и может быть использовано для измерения дипольных составляющих внешнего магнитного поля оборудования. Изобретение позволяет повысить точность измерения дипольных сферических коэффициентов g11 и X11 дипольных секреториальных сферических гармоник Х11 и Y11 внешнего магнитного поля. Для этого центры преобразователей на поверхности сферы выполнены со сферическими угловыми координатами широты и соответствующими им определенными координатами долготы, при этом магнитные оси четырех преобразователей ориентированы по направляющему орту

The invention relates to techniques for magnetic measurements and can be used to measure the dipole components of the external magnetic field of the equipment. The invention improves the accuracy of measuring dipole spherical coefficients g 11 and X 11 dipole secretory spherical harmonics X 11 and Y 11 of an external magnetic field. For this, the centers of the transducers on the surface of the sphere are made with spherical angular latitude coordinates and the corresponding longitude coordinates corresponding to them, while the magnetic axes of the four transducers are oriented along the directing unit
