Abstract:
We show that coherent magnetic field is generated spontaneously when a large domain wall is created in the early universe. It is caused by gas of two dimensional massless fermions bounded to the domain wall soliton. We point out that the magnetic field is a candidate of primeval magnetic field and suggest that the domain wall problem is solved in a model with spontaneous CP violaton by the generation of the magnetic field.
