Angular Momemtum and Large-Scale Magnetic Field in Textures Seeded   Models
  We start by pedagigically reviewing the problem of large scale magnetic fields. We explain the acquisition of angular momentum in the general context of Dark Matter models and we use this result to derive a dynamical mechanism for magnetic field generation. This mechanism does not produce any magnetic field for standard CDM, but it does for a large class of other models. We apply this mechanism in the context of the texture scenario of large-scale structure formation. Resulting constraints on the texture scenario and other models are discussed.
