Abstract

Two prototype coils were constructed using silver-sheathed (Bi,Pb)/sub 2/Sr/sub 2/Ca/sub 2/Cu/sub 3/O/sub x/ superconducting wires fabricated by the powder-in-tube technique. One was designed as a coil for an iron core magnet which generated a magnetic field of 0.2 T at 77.3 K. The other was an insert coil for a hybrid magnet which generated 0.8 T in a background field of 7 T at 4.2 K. These results suggest that Bi-based superconducting coils can be used in magnet applications.<>
