The ability of large-grain (RE)Ba sub(2)Cu sub(3)O sub(7-) delta ((RE)BCO; RE = rare earth) bulk superconductors to trap magnetic fields is determined by their critical current. With high trapped fields, however, bulk samples are subject to a relatively large Lorentz force, and their performance is...
