The interplanetary induced electric field is studied, using solar-wind time series. The probability
distribution functions (PDFs) of the electric-field components
are measured from the data and their non-gaussianity is discussed.
Moreover, for the first time we show that the electric-field
turbulence is characterized by intermittency. This point is
addressed by studying, as usual, the scaling of the PDFs of field
increments, which allows a quantitative characterization of
intermittency.
