Abstract

The present paper analyses effect of thermal processes on eddy-current losses in construction elements of cryogenic and superconducting devices. Maxwell’s equations coupled with heat-conduction equation are solved with taking into account the dependence of resistivity, heat capacity and heat-transfer coefficient on temperature. Analysis of losses as a function of magnetic field, frequency and geometry factors is given for the case of thin strip in a uniform magnetic field. It is shown that losses calculated with taking into account the thermal processes may differ from those obtained at constant temperature.
