N2  - The presence of a conducting material about an orebody modifies the transient electromagnetic fields in two ways. Firstly at the early stages by strongly directing the primary field and secondly at the later stages by swamping the target field. These effects must be recognised when interpreting field data, in view of the numerical studies of two-dimensional structures. The effects may be advantageously used in designing field measurements.
