It is assumed that the intergalactic magnetic fields were spontaneously generated in the early Universe due to vacuum polarization of non-Abelian gauge fields at high temperature T. Here, a procedure to estimate the field strengths B(T) at different T is developed and the value of B(Tew) ~ 10⁻¹⁴ G,...
