The Green Elements, often seen as an appendage to periodic tables, have an ever-growing variety of applications in modern technology. The physical and chemical properties of the Rare Earth elements contribute essential functions to a range of uses that affect our daily lives. Consider the following:
The miniaturization of cell phones, PDA’s, other mobile devices, media players such as iPod®’s, computers and computing devices, “ear bud” speakers, microphones, and a host of other items is made possible by powerful, Neodymium-based magnets. You can find other Rare Earth elements in these devices as well, for example, in the battery powering some cell phones and in the display screen of your laptop.
Hard disk drives, CD and DVD players and speakers all use Neodymium magnets.
