We show that for a large range of parameters in a SU(2)L×U(1) electroweak theory with two Higgs doublets there may exist classically stable flux tubes of Z boson magnetic field. In a limit of an extra global (1) symmetry, these flux tubes become topologically stable. These results are automatically valid even if (1) is gauged.
