Nuclear Magnetic Resonance (NMR) spectroscopy is a powerful analytical technique that can reveal the chemical structure of molecules such as organic and inorganic compounds, polymeric materials, and biological substances at the atomic level. Therefore, NMR systems are widely used from fundamental research to industrial applications. This paper introduces NMR systems, which operate on principles similar to Magnetic Resonance Imaging (MRI), a medical diagnostic imaging technology and a representative example of superconducting equipment currently implemented in society. It discusses industry trends, fundamental principles, and instrumentation, with a particular focus on superconducting magnets, which are one of the most important components of NMR systems.
