Superconducting magnetic bearing

A superconducting magnetic bearing is a device that uses the unique properties of superconductors—materials that conduct electricity without resistance—to support and stabilize a rotating object without physical contact. When cooled below a certain temperature, superconductors exhibit perfect diamagnetism, expelling magnetic fields in a phenomenon called the Meissner effect. By combining superconductors with magnets, the bearing creates a frictionless, stable support that allows smooth, silent rotation with minimal energy loss. This technology is often used in high-precision equipment like gyroscopes, turbines, or magnetic levitation systems, enhancing efficiency and longevity by eliminating mechanical friction.
