The measurements of O + ions drift velocity in the magnetotail boundary layer are used to infer the North‐South E z component of the local electric field. It is shown that E z is generally a substantial component of the field and that it reverses its sign from the dawn to the dusk side of the northern magnetotail between X SM =−15 R E and X SM =−23 R E .
