The Magnetic Field of the Milky Way (2000)
re is strong evidence that the Milky Way contains an ordered, large-scale magnetic field. The field configuration has been explored mostly by modeling pulsar (Faraday) rotation and dispersion measures.
The "face-on" view of the Milky Way shown at the left is only a schematic model of a possible configuration of the magnetic field. The arrows indicate the direction of the magnetic field, assumed to lie along spiral arms. Models like this one need to be compared to real measurements in order to evaluate how faithfully they conform to the actual magnetic field.
