In one variety of this effect, its strength can be enhanced through thermal cycling, and it has also been proposed as the basis for a bremmsstrahlung radiation source.
In one variety of this effect, its strength can be enhanced through thermal cycling, and it has also been proposed as the basis for a bremmsstrahlung radiation source. Its type II (*) manifestation  allows for flux trapping and the formation of vertices, and its characteristic penetration depth can be calculated with the London equation. For 10 points— identify this example of perfect diamagnetism in which a superconductor expels magnetic fields.
