Abstract

ABSTRACT

A formula is developed for the vertical magnetic field due to an alternating current passing through a long horizontal cable placed on a two‐layer ground. The variations of the phase and amplitude ratio of the vertical field, along profiles perpendicular to the cable line are investigated. Within the limits encountered in practice, it is found that if the upper layer is conductive, as compared to the lower layer, the phase may vary appreciably whereas the amplitude ratio changes as in the case of vacuum.
