The effect of a spherical inhomogeneity on the surface fields of a buried magnetic dipole source is determined from the reradiated fields of induced electric and magnetic dipole moments. For small spheres where the theory is valid, the errors introduced in source location are shown to be small. The results have possible application to rescue operations following coal mine disasters.
