Total power and polarization maps with a resolution of 1.13', sensitive to a weak extended emmision were obtained. In the analysiz we used also available data in the CO ans H_alpha lines. We present simple modelling results showing the imprtance of large-scale dynamo-type magnetic field present despite the strong density-wave action in this galaxy.10 pages (including 10 figures); A&A accepted (1999)Astrophysicstext
