The distribution of mean and fluctuating magnetic fields in the
  multi-phase ISM
  We explore the effects of the multi-phase structure of the interstellar
medium (ISM) on galactic magnetic fields. Basing our analysis on compressible
magnetohydrodynamic (MHD) simulations of supernova-driven turbulence in the
ISM, we investigate the properties of both the mean and fluctuating components
of the magnetic field. We find that the mean magnetic field preferentially
resides in the warm phase and is generally absent from the hot phase. The
fluctuating magnetic field does not show such pronounced sensitivity to the
multi-phase structure.
