Resumen: Infrared dark clouds, of all sizes, are the birthplace of stars. These stellar nurseries glow brightly in the submillimeter and the dust grains contained within these clouds can polarize the thermal dust emission radiation. Radiative Alignment Torque theory allows us to infer the magnetic field structure from this polarized light and therefore attempt to finally answer the question: What about magnetic fields? We observe these magnetic fields at tens of parsecs using Planck, down to sub-parsec with JCMT/ALMA and even further down to thousands of AU scales with ALMA. I will present work from two surveys, B-fields In STar-forming Regions Observations (BISTRO) and Magnetic fields in Massive star-forming Regions (MagMaR), which use JCMT and ALMA, respectively, to investigate the role of magnetic fields in star formation. Magnetic fields are compared with gravity, non-thermal kinematics (turbulence), outflows, and large-scale gas flows, with the role of magnetic fields being incredibly complex and varying across the size, mass, and age axes of star formation.
