It's the official name of the global positioning system (GPS). Contrary to what people might think, NAVSTAR is not an acronym, but actually the name given to this system by one of the most important persons from the history of GPS, John Walsh, a key decision factor when this system was first developed.
Neodymium magnets have been used in many industry branches for a very long time. Basically, neodymium (or neo) magnets are referred to as rare-earth magnets and are manufactured from a combination of three chemical elements: neodymium, iron and boron, in the Nd2Fe14B formula. The most important characteristics of neo magnets is their superior magnetic field strength; for example, a ceramic magnet should sport 18 times the size of a neo one in order to have the same power. In the audio industry, neodymium magnets are being used to increase the overall power of high-volume PA loudspeakers as well as in headphones, especially because their strength allows for miniaturization.
