We compute the net electric current generated during a first order electroweak phase transition when fermions transit from the false to the true vacuum. This current is generated by the charge parity conjugation (CP)-violating fermion interaction with the Higgs field during the phase transition and is quantified in terms of a CP-violating phase in the bubble wall separating the symmetric from the symmetry-broken phases. We comment on the seed magnetic field that this current is able to generate, and it is possible implications for magnetogenesis in the early Universe during the electroweak phase transition.
