As shown by King and Wu [12], the fields incident on thehuman body (Region 1) from a power line or VLF transmitterin air (Region 2) are conveniently separated into two parts.The fields incident on a man standing on the earth at(see Fig. 1) areand.Here,andare the fields in the central planevertically through the body at0. The part of the current inthe body induced byand[see Fig. 2(a)]is governed by an integral equation which is derived andsolved by King [14]. The part of the current induced byand[see Fig. 2(b)] can be determinedwith Ampere’s formula. As shown by King and Wu [12], the
