Neodymium and Wind Turbines
Even though the rare earth elements form the largest chemical group in the periodic table, they are generally unfamiliar and do not gain much attention. Nonetheless, the rare earth elements are crucial for many application in different fields. For instance, high technology and environmental application of the rare earth elements have been importantly developed in the past few decades. One of the most important application from the rare earth elements is permanent magnets, which do not lose its magnetic field or lose the magnetic field in a very low rate in a long period of time. The reasons give such a distinguished characteristic to the magnets is that rare earth magnets are ferromagnetic, and they have a crystalline structure. Among the other rare earth elements, neodymium with iron and boron create the most powerful magnet. This unusual strength happens because of the tetragonal crystalline structure of the compound. This powerful permanent magnet is widely used in many application, especially wind turbines, and it result in many significant profits.

Rare earth elements are the sets of seventeen chemical elements in the periodic table, specifically the fifteen lanthanides plus scandium and yttrium. They are cerium (Ce), dysprosium (Dy), erbium (Er), europium (Eu), gadolinium (Gd), holmium (Ho), lanthanum (La), lutetium (Lu), neodymium (Nd), praseodymium (Pr), promethium (Pm), samarium (Sm), scandium (Sc), terbium (Tb), thulium (Tm), ytterbium (Yb), and yttrium (Y). According to the article "Rare Earth Element”, scandium and yttrium are considered rare earth elements because they tend to occur in the same ore deposits as the lanthanides and exhibit similar chemical properties. Rare earth elements are distributed and not often found concentrated as rare earth minerals in economically exploitable ore deposits because of their
