摘要：

An optical polarization map of NGC 891, an edge-on galaxy with similar properties to the Galaxy, confirms that there are vertical magnetic fields present in the bulge/halo above the inner part of the galactic disc. We find no evidence for large-scale magnetic fields in the central dust lane, or polarization created by scattering from dust grains within the dust lane and elsewhere in the galaxy.
