A twelve-point method and a three-module measuring system for space harmonic analysis of magnetic field

Предложен метод и система измерения магнитных моментов технических объектов. Разработан алгоритм для исключения влияния наиболее весомых мультипольных помех пространственных гармоник магнитного поля на результаты измерения. Получена математическая модель измеряемого сигнала. Оценена методическая погрешность.A twelve-point method and a three-module system for magnetic moment measurement in technical objects are introduced. An algorithm for eliminating action of the most powerful multipole disturbances of magnetic field space harmonics on measurement results is worked out. Mathematical models for a measured signal and for a multiple component of the method error are developed. High accuracy of the magnetic moment measurement system, as compared with a two-module measuring system, is achieved
