The effect of self field on the critical current determination of multifilamentary superconductors

Abstract

In determining the short sample critical current of conductors of large cross section or high current density, the self-field produced by the transport current must be taken into account to obtain a true value for the critical current. A simple model calculation for determining this effect is described. Measurements on wires, cables, and monoliths show the validity and self-consistency of the procedures.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
