YBCO Levitation Disk with Magnet
PartProvides a known 90 K superconductor to confirm that the levitation check and the susceptibility coil respond before a new sample is tested. A sintered YBa2Cu3O7 disk about 20 mm across with a small NdFeB magnet shows the Meissner effect, and only strong flux-pinned levitation needs a melt-textured disk. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
