The earth holds many ultra rare elements in its crust layers, and they are used in the field of electromagnetism. The process of generating power in generators ensues from a resistance against a coil-powered force. Nevertheless, some motors today use rare earth elements such as neodymium for creating magnets with permanent strength. The benefits of such products have spread into homes and major factories as well.
While the industry continues to manufacture and use permanent magnets, their real benefit is realized in motors because they need a continuous harnessing of electricity from mechanical energy. This ensues as a natural property of the magnet, which influences a stream of electrical charges to be converted into a force to mobilize the gears. The process is similar to the way a steam engine gathers energy to push itself into motion.
Traditional wire resistors require alternative and direct current supplies in order to create motion, whereas magnets do it with alternative current only. As a result, the users of rare earth magnets need to spend little on energy bills and avoid many other items. Since you will not need slip rings for stability, the permanent type magnet will allow your apparatus to stay steady and work efficiently over a long term.
Although one finds many benefits of neodymium magnets, it is important to choose wisely for minimizing magnetic flux in air gaps. Such problems can reduce mechanical efficiency and rupturing of many parts. Moreover, the standard cost may also seem too high for many. Compared to ordinary lead and iron electromagnets, neodymium magnets cost about 1000 percent more.
High power delivery, and ease of maintenance are primary advantages of rare earth magnets. Unless manufacturing costs reduce, and sophisticated electricity systems are installed, one may find the magnets difficult to afford.
