DESCRIPTION:Magnetic fields are an importunate necessity in the formulatio
 n of a theory of star formation. Not only do they play a crucial role in t
 he fragmentation of molecular clouds and the subsequent contraction of pre
 stellar cores\, but they also significantly affect (and are affected by) t
 he dynamics of dust grains and hence the emitted radiation. I will present
  results of the first radiative\, 7-fluid\, nonideal MHD star formation si
 mulations to accurately track the evolution of a protostellar fragment ove
 r eleven orders of magnitude in density\, from the early ambipolar-diffusi
 on--initiated fragmentation phase\, through the magnetically-supercritical
  dynamical collapse phase and the magnetic decoupling stage\, all the way 
 to the nonisothermal phase\, including the formation and evolution of the 
 hydrostatic core.
