Abstract
It is shown that vertical focusing of the normal magnetic field can be performed using a quadrupole induction system. The frequency dependence of apparent resistivity calculated fr om the real part of the measured magnetic field allows effective detection of anomalously conducting objects, even in the cases wh ere the investigated object is overlapped by a thick layer with high electrical conductivity.
