Scientific paper

The BSA FIAN radio telescope was used to investigate the spatial variations of the Galactic radio background at a frequency of 102.5 MHz in the region adjacent to the North Galactic Pole. An analysis of the two-dimensional correlation function of the radio emission intensity made it possible to estimate the characteristic angular scale of the Galactic magnetic field inhomogeneities (about 8 deg) and the ratio of the strength of the regular magnetic-field components (normal to the line of sight) to the random field (about 1). The direction of the vector of the regular magnetic field is close that of the Galactic spiral arm.
