Mapping magnetic fields from clouds to cores with PRIMAger
High-resolution, wide-area mapping of magnetic field geometries within molecular clouds, including the star-forming filaments and cores within them, is crucial to understanding the role of magnetic fields in the star formation process.

We, therefore, propose an unbiased survey of star-forming molecular clouds within 0.5 kpc of the Earth in polarized light with the PRIMAger Polarimetry Imager. We will map magnetic fields over entire molecular clouds at linear resolutions of ∼10<sup>−3</sup> to 10<sup>−2</sup> pc (∼10<sup>3</sup> to 10<sup>4</sup> au) in PRIMAger Bands PPI1 to PPI4, thereby resolving magnetic field structure both within individual star-forming filaments and cores and in the most diffuse regions of molecular clouds.

This time estimate can be simply scaled up to map magnetic fields in a larger sample of molecular clouds, including more distant regions of higher-mass star formation.K.P. is a Royal Society University Research Fellow, supported by grant number URF\R1\211322.
