A numerical approach for solving forward electromagnetic induction problem has been suggested. It takes into consideration the terms involving the conductivity gradient. Some numerical solutions are presented for conductivity models containing narrow bellshaped zones in which the electrical conductivity varies very strongly. These zones of anomalous conductivity variations at depths of 100 or 600km influences the shape of response functions in the period range from 1 to 100 days.
