The interpretation of experiments devoted to searching for effects

of electromagnetic $\nu e$-scattering due to anomalous magnetic moment

$\mu_\nu$ of massive neutrinos is discussed. It is shown, that the value

of $\mu_\nu$ cannot be determined undoubtly in these experiments if the

mass of the neutrino in unknown. The effective cross section of the

electromagnetic $\nu e$-scattering of Dirac relativistic neutrino

coincides with the cross section of scattering on the electron for the

charged lepton without the anomalous magnetic moment, but with the

effective electric charge $e_{\nu_{ef}} \leq 10^{-9} e$. This conclusion

can be understanded as the consequence of structure effect resulting from

the relativistic correction for Zitterbewegung of neutrino. It is shown,

that radiative processes may be neglected when the massive neutrino

interacts with the substance. The calculations of the elastic $\nu

e$-scattering cross sections and the radiative electromagnetic $\nu

e$-scattering cross sections in the framework of the quasiclassical method

are given in the appendices. Moreover the qualitative neutrino model which illustrate the sence of the neutrino effective electric charge is

proposed.
