Abstract :
Quasi-permanent magnets made of melt textured yttrium barium copper oxide (YBCO) superconductor can now trap multi-Tesla fields and retain that field semi-indefinitely. Because the fields so trapped achieve near zero creepage decay, they can be used as replacements of permanent magnets. This paper investigates the fields expected from these magnets, their prediction, and design expectations when they are incorporated into large scale arrays.
