The electromagnetic fields about an electric wire source of an arbitrary finite length are usually calculated by numerical integration of the dipole field equations along the length of the wire (Scriba, 1974; Anderson, 1974). However, many of the required integrals for the fields over a multilayered half‐space can be solved analytically. The integrations may also be extended to solve for the fields about an infinitely long wire source. In so doing, it becomes clear which portions of each field component are produced by the wire and which are produced by its grounded ends. Although the horizontal electric fields of a finite wire source have been derived previously (Sunde, 1949), the complete field equations for a finite‐length wire appear here for the first time in explicit form.
