Abstract
In weakly ionized astrophysical plasmas, shear flow induced plasma — neutral gas friction yields self-generated magnetic fields of seed-field order. This process is of cosmological importance and relevant for protogalactic systems like Lyα-clouds. In our contribution we illustrate this mechanism by the help of 3-dimensional 2-fluid simulations of primordial rotating gas clumps in Lya-clouds showing that plasma — neutral gas interactions cause large scale magnetic fields of the order of 10-15 G on time scales of the order of 106 yrs.
