Методология экспериментального определения сферических гармоник магнитного поля технических объектов

Abstract

A comparative analysis of methods for the experimental determination of the spherical harmonics of the magnetic field of technical objects has been carried out. The fundamental principles for creation of spherical harmonics of the magnetic field have been represented. The interrelation of the established principles with metrological means of measuring of spherical harmonics of the magnetic fields is shown. A classification of the methods for separating of contributions and determining the magnitudes of the coefficients of the spherical harmonics of the magnetic field is proposed. It is proposed to use the classification as a theoretical basis for creating new methods and means for conducting a practical spherical harmonic analysis of the magnetic field of technical objects.
