Resin-impregnated bulk melt-processed high-T c materials have already been used for several practical applications to improve the mechanical performance. A large electromagnetic force acts on the superconductors when they trap large magnetic fields, which occasionally leads to device failure. Epoxy resin can penetrate into the bulk superconductors in certain conditions. Taking advantage of the new technology, a compact, lightweight, and mobile permanent high-T c superconducting magnet system was designed and built using melt-processed GdBa 2Cu 3O y rings. The maximum trapped field inside the annular magnet reached 0.75 T to 2.59 T, for one to ten rings, respectively. The results clearly demonstrated that one can construct a permanent magnet system using the melt processed LREBa 2Cu 3O y compounds. The use of simple superconducting permanent magnet for magnetizing bulk melt-processed materials can open new technological windows in various industrial areas, particular in medicine, railways, space, or naval transport systems.
