Summary

The radiation from most pulsars has a high degree of linear polarisation, allowing measurements of Faraday rotation. Such radio observations of polarisation provide detailed measurements of the interstellar magnetic field along the line of sight to a pulsar, including the fields along the spiral arms and the large-scale field outside the plane of the Galaxy. Pulsars can probe the magnitude and direction of the galactic magnetic field.
