Thermoelectric current in a superconducting circuit

The problem of a thermoelectric current in a closed circuit of two different superconductors is considered. A solution is found that describes the distribution of field and currents about the cross section of a long nonuniformly heated, inhomogeneous cylinder. The generally accepted model for the current distribution (see Ref. 1 for a Review) is shown to be valid and the conclusions of Pickett to be erroneous. The connection of the theory to experiment is discussed.
