Neodymium is not found naturally in its metallic form — it must be separated from lanthanide mixes. This element has incredibly strong magnetic properties, and is used to create the strongest rare earth magnets available by weight and volume. Praseodymium, another rare earth, is also often found in such magnets, while dysprosium is added to improve the functionality of neodymium magnets at higher temperatures. This type of magnet has revolutionized many mainstays of modern technology, such as cell phones and computers. Indeed, due to how powerful the magnet is even when produced in small sizes, neodymium has made the miniaturization of many electronics possible, according to the Royal Society of Chemistry. Certainly, while rare earths may sometimes be grouped together, neodymium stands out as an especially important material among the rest.
