Abstract
Transport ac losses of a rectangular thin strip obeying relation E/Ec=(J/Jc)n with a fixed critical current Ic and n=5,10,20,30, and 40 are accurately computed at a fixed frequency f as functions of the current amplitude Im. The results may be interpolated and scaled to those at any values of Ic,f, and 5⩽n⩽40. Normalized in the same way as that in Norris’ analytical formula derived from the critical-state model and converting f to a critical frequency fc, the modeling results may be better compared with the Norris formula and experimental data. A complete set of calculated modeling data are given with necessary formulas to be easily used by experimentalists in any particular case.
