Mapping the structure of interstellar magnetic fields in the cold gas of nearby galaxies is crucial to understand how magnetic fields influence gas dynamics in galaxies, and in particular the role of the field in regulating star formation, driving galactic outflows, and fuelling galactic nuclei. In this contribution, I will present our group's ongoing efforts to map the magnetic field structure in several nearby and Local Group galaxies using dust polarization measurements by PILOT, ALMA and Planck, and review opportunities for progress with NIKA2 and the BeBOP instrument on SPICA.
