The broken-symmetry electroweak vacuum is destabilized in the presence of amagnetic field stronger than a critical value. Such magnetic field may begenerated in the phase transition and restore the symmetry inside thebubbles. A numerical calculation indicates that the first-order phasetransition is delayed but may be completed for a sufficient low value of theHiggs mass unless the magnetic field is extremely high.
