Summary

Using an alternating-current magnet fabricated from this wire, current operation at 60 hertz and 4.2 K was effected, and steady-state operation at a capacity of 104.8 kilovoltamperes, a current of 105.8 A (rms) and a voltage of 991.2 V (rms) was achieved. At the same time, a central magnetic field of 2.5 T was obtained. Loss measurements confirmed the effectiveness of reducing magnet size through the use of wires having high-current density.
