Abstract
The information on the spatial distribution of a magnetic field in a rather large volume is needed, for example, in magnetic-resonance tomography, when it is important to have a uniform magnetic field in the working region of a tomograph. The stages of the optimization of a magnetic-field sensor, which is used to adjust the magnetic-field homogeneity, are described. These stages are aimed at a decrease in the measurement errors that are associated with the parallel registration of several harmonics, which constitute the magnetic field. The results of calculations on the mathematical modeling of various configurations of the magnetic- field-uniformity sensor and the practical implementation of the chosen variant are presented.
