| Research Abstract |
The transport current loss of superconductor with ripple current was theoretically estimated. In this calculation, the decrease of the critical current density by self-magnetic field was taken into account. In addition, finite element method was used for the estimation of transport current loss. As the result, it was confirmed that the transport current loss is enough small for the case of small ripple current amplitude.
