Classification magnet magnet can be grouped into "permanent magnet" and "non-permanent magnets." Permanent magnet may be a natural product, known as lodestone, also be made artificially produced (the strongest magnets are neodymium magnets). The non-permanent magnets, magnetic only under certain conditions there, usually in the form of an electromagnet to produce, i.e. the use of electric current to strengthen the magnetic field. Magnet magnetic molecules into the interior of the magnet is not magnetized magnet (magnet molecular theory) are randomly arranged, arranged in the magnetization process after the magnetic molecules have rules. In this case, N pole and S-pole magnetic molecules will be facing in the same direction so that the magnet has a magnetic and become magnets. Meanwhile nave tool magnet manufacturers, the existence of the opposite poles of the magnetic poles and an equal amount on the same magnet. For heavy machinery industry, or for use in large-scale power units, this also decent. But in today's electronic age mayong tool crafted magnet manufacturer, we need a more exquisite stature magnet. But how can we create such a magnet to it? A lot of solid material in electronic and spin interactions between them are too complicated, theoretical physicists want to accurately determine their behavior, almost no chance of winning. Therefore tool magnet manufacturers, manufacturers better magnet relies heavily on the dark magic metallurgists: mixing the various possible elements, and then into the magnetic field, to see how the wheel of fortune will change. Shen Nong tasted a hundred herbs such methods have been tested. 1930s synthetic aluminum - cobalt - nickel-magnet, the energy density is twice that of the best ferrite magnets. But the real breakthrough is still above the 1970s discovered called lanthanides or rare earth elements, beginning with the magnetic potential. These elements in the periodic table is always a separate area, without exception, can contribute a lot of spin parallel to each other and even woven into a piece of electronics. With a mixture of cobalt and rare earth magnets made of samarium, storage or even than aluminum - cobalt - nickel-magnet even twice as high.
