Scientific paper
Recent investigations suggesting that amplification and regeneration of large scale magnetic fields can result from the combined action of galactic winds and magnetic diffusion are described. Observations of polarized radio emission from spiral galaxies imply the presence of magnetic fields organized with axisymmetric or bisymmetric structure on the scale of the whole galaxy. Such fields were explained previously either as a systematic patterning of primordial fields by differential rotation or as the result of dynamo generation of large scale components from non-mirror symmetric turbulence. A model for the phenomenon based on magnetic field regeneration by the interaction between turbulent diffusion and axially and radially sheared galactic winds is summarized.
