The Ehrenfest's Paradox and Radial Electric Field in Quasi-Neutral   Tokamak Plasma
  A relation between physical consequences of the so-called Ehrenfest's Paradox and the radial electric field in the classical quasi-neutral tokamak plasma is shown. Basic author's approach to the relativistic nature of the tokamak has been described in [1]. The experiment which can resolve the Ehrenfest's Paradox is presented.
