Abstract
Cosmological phase transitions accompanied by some kind of symmetry breaking
would cause the creation of topological defects and the resulting production of primordial
magnetic field. Moreover, such a procedure inevitably affects the cosmic background radiation
and it may be observed today. Motivated by the existence of stabilized embedded defects
in the standard model of elementary interactions, we discuss their application to
the cosmological electromagnetic field generation.
Key words:
cosmology; defect; pion string; magnetic field.
