Various methods of magnetoelectric effect excitation in a composite structure consisting of ferromagnetic and piezoelectric layers are investigated and compared, such as: by ac magnetic field of electromagnetic coil, by ac current flowing through external conductive strip, by ac current flowing through the ferromagnetic layer, and by as current flowing through electrode of the piezoelectric layer. It is shown that ac current flowing through the ferromagnetic layer effectively excites both linear and nonlinear magnetoelectric effects due to absence of demagnetization. Specific dependence of the voltage harmonics on the permanent magnetic field under the structure excitation by ac current are observed and explained.
