Abstract
The local temperature and heat current density in a superconducting strip whose ends are maintained at constant temperature are calculated for the case of periodically repeating motion of magnetic-flux-containing normal regions along the strip. The effective transport entropy per unit length per flux quantum, associated with the motion, is calculated; reasonable agreement with experiment is found. The power dissipation arising from the presence of temperature gradients is found to be small by comparison with the electrical dissipation in pure, but not in impure, superconductors. The presence of local thermal gradients is estimated to have an important influence upon the thermogalvanomagnetic effects in superconductors.
