Superconducting Magnetic Levitation

Superconducting magnetic levitation occurs when a superconductor, a material that conducts electricity without resistance at very low temperatures, interacts with a magnetic field. When cooled below its critical temperature, the superconductor expels magnetic fields (Meissner effect) and can trap magnetic flux lines. This creates a strong, stable magnetic attraction that can lift and suspend objects, allowing them to float with little to no friction. This technology enables applications like frictionless train transportation and precise magnetic systems, leveraging the unique properties of superconductors to achieve efficient, contactless levitation.
