We analyze the case of a strong field and low temperatures as compared with the W rest energy. If the magnetic field is large enough, it is self-consistently maintained. Charged vector bosons play the most important role, leading only to a decrease of the symmetry breaking parameter, the symmetry restoration not being possible.Presented in the First International Workshop on Astronomy and Relativistic Astrophysics (IWARA 2003), Olinda, BrazilHigh Energy Physics - Phenomenologytext
