Abstract
A laminated superconductor wire includes a superconductor wire assembly, which includes a first superconductor insert comprising a first high temperature superconductor layer overlaying a first substrate and a second superconductor insert comprising a second high temperature superconductor layer overlaying a second substrate. The first and second superconductor inserts are joined together at their respective substrates. An electrically conductive structure substantially surrounds the superconductor wire assembly.
