Walther Meissner

Walther Meissner was a German physicist known for his work in low-temperature physics, particularly for discovering the Meissner effect in 1933. This phenomenon occurs when a material, specifically a superconductor, expels all magnetic fields from its interior when cooled below a certain temperature. As a result, a magnet placed above a superconductor will levitate, showcasing a unique property of superconductors. Meissner’s discovery was crucial in understanding superconductivity and has implications for advanced technologies, such as magnetic levitation in transportation and powerful computing systems.
