Abstract
A simple kinematic model has been applied to simulate the evolution of the interstellar magnetic field permanently twisted by turbulent gas motions accompanied by effects of the field diffusion. The magnetic field was found to develop well-ordered twisted structures over the whole gas parcel analyzed. This field configuration has a preferred sense of twisting dependent on the helicity of the gas flow. The model of synchrotron emission and polarization of M31-like galaxy containing magnetic field structures taken from our simulations reproduces quite well its basic observed radio and polarization properties.Keywords
