Nineteen deep geomagnetic soundings were made in NE Poland which belongs to the East European Platform. The calculated transfer functions show that the induction vectors are quite large, achieving 0.8. The maximum length of the vectors is at the period of about 300 s. Comparing the directions of the induction vectors with the map of the thickness of sedimentary cover we found a striking correlation with the crystalline basement depth isolines. An auxiliary 2D modelling and a thin-sheet model support the statement that substantial part of the vectors is due to induction in the sedimentary cover.
