Viscous Bianchi type II universes with intergalactic magnetic field

Homogeneous Bianchi type II models are studied for universes containing a viscous fluid and a large scale magnetic field. The present values of the magnetic field, the anisotropy in the microwave radiation background and the Hubble parameters are obtained by numerical integration of the Einstein and Maxwell equations from the beginning of the lepton era (1012 K) up to the present (2.7 K). It is found that an inflationary scenario combined with a Bianchi type II geometry leads to data that conflict with observation.
