Potentials in Spinning Rotor Follow Dessler Predictions

Jesse W. Beams (University of Virginia) has measured the electrical strains in a fast rotor. His results show that the periphery becomes slightly positive with respect to the axis and appear to agree with the theories of Alexander J. Dessler and colleagues and Conyers Herring rather than those of Leonard I. Schiff and M. V. Barnhill. The subject has become controversial in an effort to calculate the fields experienced by freely falling electrons in a vertical shielding cylinder.
