A great multidisciplinary application of physics and other sciences. And example of a “pure science” discovery given a practical application. Based on NMR – Nuclear Magnetic Resonance – discovered in the 1940s. all magnets have magnetic poles – . . points at the ends of a magnet that have opposing magnetic qualities. all magnets have a north pole and south pole that are magnetically opposite. like poles repel and unlike poles attract.
