Abstract

The effect of a perfectly conducting prolate spheroid on the surface fields of a buried vertical magnetic dipole is examined in the quasi-static case. When the spheroid is in the vicinity of the source and near the surface, the errors introduced in source location can be significant. The results have possible application to rescue operations following coal mine disasters and in similar situations.
