Due to the presence of the magnetic field, the initial singularity shows ``oscillatory'' features reminiscent of the Bianchi Type--IX case. The Bianchi Type--I models with a magnetic field are therefore a counterexample to the folklore that matter fields can be neglected in the vicinity of the singularity.6 papes, Proceedings of the 12th Italian Conference of General Relativity and Gravitational Physics, style includedGeneral Relativity and Quantum CosmologyAstrophysicstext
