The orthogonal conductivity of a toroidal plasma is calculated in the fluid regime. If the damping time for toroidally directed angular momentum is tau/subN/, the orthogonal conductivity is shown to be sigma/sub perpendicular/= (rhoc$sup 2$/B$sup 2$/subp/)/tau/subn/ for large tau/subN/. Here rho is the mass density, c is the speed of light, and B/subp/ is the poloidal component of the magnetic field. For large tau/subN/, the flow induced by the orthogonal electric field is almost purely toroidal and of magnitude c (E/subr/-E$sup 0$/subr/)/B/ subp/ where E$sup 0$/subr/ is the electric field required for ambipolar diffusion.
