Flux pinning

On a simple 76 millimeter diameter, 1-micrometer thick disk, next to a magnetic field of 28 kA/m, there are approximately 100 billion flux tubes that hold 70,000 times the superconductor's weight.

The worth of flux pinning is seen through many implementations such as lifts, frictionless joints, and transportation.

The thinner the superconducting layer, the stronger the pinning that occurs when exposed to magnetic fields.

MagSurf was developed by the Paris Diderot University utilizing flux pinning to create a hoverboard-like effect that could transport a person, demonstrating the usefulness of the technology.

[3][4] The Federal University of Rio de Janeiro has also been developing a flux pinning-based MagLev system called Maglev Cobra, which aims for a smaller form factor than existing urban rail systems.
