Neodymium
Your cell phone, portable CD player, computer or sound system would not exist in their current form without the use of strong permanent magnets made possible by Neodymium. Today, more and more electronics applications realize the benefits of Neodymium Iron Boron (NdFeB) permanent magnets that allow for the miniaturization of a variety of technologies. These permanent magnets, which maximize the power/cost ratio, are used in a large variety of motors and mechanical systems. Cellular phones contain both neodymium magnets and capacitor, which produce powerful electronic generation and boost the power of these communication devices.

At the heart of anti-lock brakes (ABS), air bags and many other systems dependent on electric motors in the modern vehicle are small powerful permanent magnets based on Neodymium. Modern, anti-glare automobile light glass and mirrors also utilize Neodymium.

Neodymium oxide can be added to CRT glass to enhance picture brightness by absorbing yellow light waves. Neodymium has a strong absorption band centered at 580-nm wavelength which helps clarify the human eye's discrimination between reds and greens. The oxide also has a sky-blue color and is used in the production of various coloring pigments for products such as ceramic tile and artistic glass. Neodymium compounds help to stabilize electrical properties in ceramic capacitors.

Many solid state lasers use Neodymium because it has an optimal selection of absorption and emitting wavelengths. Neodymium lasers are used in material processing, drilling, spot welding/marking and medicine, where the Neodymium light laser is the instrument of choice for non-evasive surgical procedures because of the easily seen high intensity blue focal point light. The non-ionic radiation MRI (magnetic resonance imaging procedure) uses magnetic wave generation that is solely dependent on the Neodymium magnet.
