Abstract

This paper investigates the suitability of MgB₂ tapes clad in a high magnetic permeablity iron sheath for use in practical multi-turn superconducting coils. The flux-density in the MgB₂ portion of a single filamentary tape under various configurations is analyzed and its effect on the critical current capability is evaluated. The magnetic field is computed numerically using the finite element (FE) method. The FE model used for the analysis is described along with the assumptions made. The results indicate that the iron-clad MgB₂ tapes are undesirable for SC coils in many practical applications from a steady state performance stand point.
