The invention relates to a device for the non-destructive testing of an electrically conductive part comprising: - an induction portion, and - a receiving portion, - treatment means, in which the induction portion comprises an inductor dissociated into n layers (33) supplied at different frequencies f1, f2,..., fn, in which the receiving portion comprises several magnetic receivers (34) supplied at frequencies f1', f2',..., fn' connected to one another in at least one column, each magnetic receiver (34) being positioned under a layer, the indices n and m being integers = 2, and in which the treatment means make it possible to know the magnetic field in each of the magnetic receivers (34) of a column. |
