| Definition: | massive superconductor with large enough size except wires, tapes and thin films Note 1 to entry: This superconductor is often used as a superconducting quasi-permanent magnet with trapped magnetic flux, and its size is typically larger than 10 mm in a larger dimension. Note 2 to entry: Bulk superconductor with trapped magnetic flux is used as permanent magnet for levitated system, water purification system, etc.
