The Magnetic Field of the Large Magellanic Cloud: A New Way of Studying   Galactic Magnetism
  We present a study of the Faraday rotation of extragalactic sources lying behind the Large Magellanic Cloud. These data represent the most detailed study yet of magnetic field structures in any external galaxy, and are a demonstration of how magnetic fields in galaxies will best be studied with future instruments.
