Local galaxies are in a state of energy equipartition which means that the kinetic energy density equals roughly the thermal one and the magnetic one. ... In models of young galaxies magnetic fields are usually not considered as they are assumed not to be dynamical important at high redshifts. In the presence of turbulence, however, the turbulent dynamo can amplify weak magnetic seed fields by randomly stretching, twisting, and folding the field lines. ...
