Composite superconductor body and magnetic levitation system

摘要

A superconductor composite body for diamagnetic levitation above a magnet track (4) has superconductor elements (1) made of high temperature superconductive material and having for example a cross-sectional dimension of at least 1 mm. The superconductor elements (1) are embedded in or laminated to an electrically conductive non-magnetic material (2) to form an integral composite body, which can be cooled by liquid nitrogen (7). High driving force can be obtained with coils (5). Lateral guidance is obtained by use of high magnetic hysteresis superconductive material. $$
