Question 5 of 5
5. Question
Rare earth elements are crucial for the following EXCEPT:
Correct
Answer: C
Explanation:
Rare earth elements (REEs) are crucial for many modern and green technologies due to their unique magnetic, optical, and electronic properties. However, they are not a primary requirement for the traditional process of natural gas extraction.
1. Wind turbine generators: REEs like neodymium, praseodymium, dysprosium, and terbium are essential for the high-performance permanent magnets used in most large wind turbine generators, especially direct-drive offshore turbines, due to their efficiency and compact size.
2. Electric vehicle motors: More than 70% of electric vehicle (EV) motors use permanent magnets made from REEs (such as neodymium-iron-boron magnets) to achieve high efficiency, power density, and torque.
3. High‑performance electronics: REEs are used in numerous high-tech devices, including smartphones, computer hard drives, flat-screen displays, and various other consumer and military electronics, for their unique properties in phosphors, catalysts, and magnets.
