Аннотация:The thin-disk galactic dynamo model of Baryshnikova et al. (1987) is used to obtain magnetic lines for the axisymmetric m = 0 and nonaxisymmetric m = 1 dynamo modes. Measurements of pitch angles for magnetic lines in the outer parts of galaxies are employed to determine the ratio of the energy-range scale of interstellar turbulence to the thickness of the ionized gaseous disk. Possible explanations for the presence of bisymmetric fields among the observed magnetic structures are considered.
