Abstract

ABSTRACT

As an extension of the eddy current pattern computed by Koefoed and Kegge (1968) for a thin vertical infinitely‐conducting half‐plate in presence of oscillating magnetic dipoles, this paper computes the contribution to the (electro‐) magnetic anomaly at the receiver by each element of the vein separately. Twelve contour diagrams for such elemental contributions are presented as samples. Two points of general interest stand out: (1) The contributions from different portions of the vein are not all of one sign; the contribution from one part may cancel that from another; and (2) The portion of the vein nearest to the transmitter‐receiver system does not necessarily make the largest contribution to the total measured signal.
