Method and system for measuring zonal harmonic of the octupole magnetic moment of external magnetic field

Raqi Alrawashdeh
Annotations languages:

The study based on the modeling of the external magnetic field source by a spatial harmonics – multiples. In result for the first time the point magnetometric method of measuring magnetic octupole moment is developed. The method is based on measuring the component of the magnetic field strength, in particular for zonal harmonics, in the twelve points of space with defined coordinates and determining from the measurements octupole magnetic moment with the determination of the magnitude of the zonal harmonics in any precise space.
Keywords: zonal harmonic, octupole magnetic moment, tension of magnetic-field, point magnetometer method, dipole magnetic moment, quadrupole magnetic moment
