Popis: The features of the longitudinal inhomogeneity of the solar magnetic field strength in the region of its generation at mid-latitudes are investigated. For this purpose, the configuration of the large-scale magnetic field was analyzed, which is determined to the greatest extent by its strength. Model calculations have shown that the large-scale magnetic field of the Sun is created by local sources at areas where the generated magnetic field emerges. The source parameters derived from the calculations indicate a significant longitudinal variation of the analyzed field strength. The first harmonic, with one maximum and antipodal minimum, appeared to be the determining one in such a variation. The longitudinal positions of maxima and minima in the northern and southern hemispheres are the same, which indicates the simultaneousness of the generation of the solar toroidal field. The difference between the maximum and minimum can range from 4 to 10 in terms of the values of the magnetic moments of local sources of the large-scale solar magnetic field.
