Electric field E{sub r} transverse to the current in a moving quasi-neutral plasma can (and should) be considered using Poisson equations and densities of volume charges emerging in the plasma. In the general case, E{sub r} becomes nonlocal; i.e., remote volume charge densities are not screened but affect the formation of E{sub r} at the points under investigation. This approach is used for describing a phenomenological theory of radial electric field E{sub r}(r) and velocity of toroidal rotation of the plasma in the tokamak. Examples of application of this theory to actual experiments are considered.
