Cosmological phase transitions in the early universe lead to gradients in the vacuum expectation value of the Higgs field. The variation of the Higgs field results in the presence of electromagnetic fields after the completion of the phase transition. This mechanism would also produce magnetic fields of other unbroken gauge symmetries such as SU(3)c. We estimate the strength of the electromagnetic fields produced due to the electroweak phase transition.
