Magnetic Flux Pinning

Magnetic flux pinning is a phenomenon observed in superconductors, where magnetic field lines become trapped in specific locations within the material. This occurs when the superconducting state allows the material to resist changes in its magnetic field. As a result, superconductors can maintain their position relative to magnetic fields, effectively "locking" them in place. This property is crucial for applications like magnetic levitation, enabling trains to float above tracks with little friction, providing faster and more efficient transportation. Magnetic flux pinning plays a significant role in advancing technologies like sensors and energy storage systems.
