Using a wavelet-based technique for cross-correlation signal analysis and filtration, we show that at frequencies lower than the frequency of the applied magnetic field, the spectral properties of the velocity field can be clearly seen in spite of the fact that the measured fields are much weaker than the driving rotating (or traveling) magnetic field. On the basis of the proposed method, spectra of turbulent velocity fields, measured in the experiment, were studied.
