The substances are used in a wide range of products including smartphones, airplanes, and medical devices, as well as military gear such as stealth technologies, radar, and night vision goggles. Neodymium, for example, is used to make magnets found in smartphone speakers and haptic feedback devices, while terbium is used to make solid state hard drives.
