DESCRIPTION:Magnetic fields are ubiquitous across cosmic scales\, yet thei
 r role in galaxy formation remains elusive. In this talk\, I show that pri
 mordial magnetic fields\, originating before the end of recombination\, ca
 n amplify small perturbations\, accelerating the collapse of the first dar
 k matter halos. This results in an early onset and efficient star formatio
 n\, consistent with JWST observations. However\, primordial fields are not
  the only source of magnetization at high redshifts. Using RAMSES-RTMHD co
 smological simulations\, I compare the role of primordial fields and AGN-d
 riven outflows in shaping the magnetic landscape of the high-redshift univ
 erse.
