We show that plasma - neutral gas friction in a weakly ionized rotating protogalactic system creates magnetic fields of seed field order. For these purposes we present results of 2-fluid simulations. Considering primordial gas clouds, this mechanism yields a magnetic field of the order of on time scales of and spatial scales of several hundred parsec. Such fields are a reasonable input for further amplification processes.
