Magnetic field induced by currents flowing through ground between buried pipe and an earth contact electrode is analyzed and numerically evaluated under the assumptions of homogeneous soil of pure resistance and quasi-steady field, in order to clarify and to increase the accuracy of alternating magnetic field location technology, Previous formulas are generalized. The time required for the evaluation is reduced very much by the development of a table look up algorithm. Experimental measurement of magnetic fields on an open space agree well with the numerical evaluations, inspite of the fact that the idealized assumptions are hardly met in practice.
