This Joint Legacy Program aims to construct a comprehensive empirical picture of the magnetic field strength and structure in the multiphase ISM of galaxies. For the first time, we will construct a FIR polarimetric survey of nearby galaxies. We will combine these results with radio polarimetric and optical spectroscopic observations to obtain magnetic field strength/structure and gas dynamics as a function of host galaxy properties and kpc-scale galactic environment. The wide-field, multi-wavelength polarimetric observations from this Legacy Program will be a transformative leap that will establish the foundational framework of the kpc-scale magnetic field structure in the molecular gas disks of nearby galaxies.
