Magnetic Levitation and Superconducting Applications
Year: 2025
Type: article
Abstract: Superconductivity and magnetic levitation represent two of the most transformative concepts in modern physics and engineering. Superconductors, characterized by zero electrical resistance and the Meissner effect, allow magnetic fields to be expelled or trapped in a manner that produces frictionless, stable levitation. This principle underpins revolutionary applications ranging from maglev trains capable of speeds exceeding 600 km/h, to magnetic bearings, flywheel energy storage, and precision devices requiring contactless operation. The thesis begins with the fundamentals of superconductivity (Chapter 1), explaining the phenomena of zero resistance, flux quantization, and type-I vs. type-II behavior. In Chapter 2, the principles of magnetic levitation are explored, including electrodynamic suspension, electromagnetic suspension, and the role of superconductors in providing stability through flux pinning. Chapter 3 focuses on materials science, examining both low-temperature and high-temperature superconductors, their fabrication, and engineered pinning centers critical for stable levitation.
