Abstract

Total AC losses in multi-filamentary, silver-sheathed Bi2Sr 2Ca2Cu3Oy (Bi-2223) tape were measured as functions of transport current, applied magnetic field and frequency by electromagnetic and calorimetric methods. Results of both methods agree well with each other. The calorimetric method was employed to investigate the effect of the phase difference between transport current and applied field, Δφ, on total AC loss. Total loss changes significantly with Δφ when applied magnetic field is perpendicular to the surface of the sample. The effect of Δφ on total loss in parallel magnetic applied field is smaller.
