Illustration of magnetic levitation using a high-temperature ceramic superconductor. A magnetised cube is floating freely above a nitrogen-cooled slab of the superconducting ceramic. Discovered in 1986, the superconducting ceramics are expected to lead to a technological revolution and are the subject of intensive worldwide research. Superconductors lose all of their electrical resistance when cooled below a certain threshold temperature. | |
