<p><P>PROBLEM TO BE SOLVED: To actualize an increase in current capacity and low AC loss by suppressing a drift more than before by easily performing dislocation with less strain influence on a wire rod than before. <P>SOLUTION: A superconducting coil 1A is formed by forming a first coil 3 and a second coil 4 in a double-pancake shape, the coils being obtained by bundling and winding two superconductive tape wires 2, and only two superconducting tape wires 2 disposed in innermost layers of the first coil 3 and second coil 4 are replaced with each other at one optional place in a circumferential direction. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
