The Magnetic Field in IC 342
Late-type galaxies feature spiral structures with large pitch angles where phenomena in spiral arms can easily be studied. IC 342 is an outstanding late-type galaxy because of its large angular size (50’ in radio continuum, 90’ in neutral hydrogen gas) and its favourable inclination of only 25° to the line of sight . This allows a detailed study of the magnetic field in the spiral arms of IC 342 even with the medium resolution achievable with the 100-m radio telescope at centimetre wavelengths. The largescale structure of the magnetic field in IC 342 was earlier suggested to be ring-like  similar to M31.
