Motorcycle turn the magnet

We are talking about magnets, generally refers to the permanent magnets. The permanent magnet is divided into two major categories. 5.2 The first category metal alloy magnets include neodymium magnets Nd2Fe14B), samarium cobalt magnets (SmCo), aluminum-nickel-cobalt magnets (ALNiCO) 5.3 The second category of ferrite permanent magnet material (Ferrite) 1. NdFeB magnets which is found in the commercialization of the highest performance magnets, known as magnetic king, have extremely high magnetic its biggest energy product (BHmax) higher than the ferrite (Ferrite) more than 10 times. Machining performance itself is also very good. Operating temperature up to 200 degrees Celsius. And its hard, stable performance, good price, so its application is extremely broad. But because of its chemical activity is very strong, it must deal with its surface coating. (E.g. plating Zn, Ni, electrophoresis, passivation, etc.). 2. It is the main raw materials include ferrite magnets BaFe12O19 and SrFe12O19. Manufacturing method made by ceramic technology, texture rather hard, is a brittle material, since the ferrite magnets have good temperature resistance, low cost, moderate performance, has become the most widely used permanent magnets. 3. Alnico magnet is an alloy of aluminum, nickel, cobalt, iron and other trace metal elements. Casting process can be processed into different sizes and shapes, very good processability. Cast aluminum nickel and cobalt permanent magnet has a low reversible temperature coefficient, working temperature up to 600 degrees Celsius. Alnico magnet products are widely used in various instruments and other applications. 4. Samarium cobalt (SmCo) on the basis of different components into SmCo5 and Sm2Co17. Because of its materials are expensive and their development is limited. Samarium cobalt (SmCo) as a rare earth permanent magnet, not only has a higher energy product (14-28MGOe), reliable coercive force and excellent temperature characteristics. Compared with NdFeB magnets, SmCo magnet is more suitable for working in high temperature environments. 5.4 permanent magnet permanent magnet may be a natural product, known as lodestone, also be made artificially produced (the strongest magnets are NdFeB magnets). 5.5 Non-permanent magnet: non-permanent magnet is heated to a certain temperature suddenly loses its magnetism, which is due to the large magnet arrangement consisting of "meta magnet" and from order to disorder caused; put into a magnet loses its magnetism a magnetic field, when the magnetization reaches a certain value, it is magnetized arrangement "Yuan magnet" in and from disorder to order. 5.6 Artificial artificial magnet Magnets: horseshoe magnet and bar magnet into, is that we live in the most common, in which the more popular horseshoe magnet. Sided magnet magnetic means one side, the other side of the magnetic weak magnet, the method is treated with a special wrap-sided galvanized iron to one side of the magnet, so that one side of the magnetic shield will be wrapped, magnetic is refracted to the other side, the other side of magnetically enhanced. If only one side of the case with a magnetic, if the other side can cause damage or disturbance magnetic; some occasions, such as a magnet on the box only need one side of the magnetic, the other side is optional, there is no use of magnetic, Such single-sided magnetic greatly reducing costs and saving material. Sided magnet magnetic signals refracted as refracted satellite pot or pan flashlight bulbs to light refraction, the refraction effect is mainly determined by the following three aspects: 1 material: the choice of materials and thickness, and spacing of the magnet and the material has a close relationship. Pure iron is easy to MFL, special treatment refraction will increase, but not 100% shielding material developed, but the effect of different manufacturers make different materials. 2. Angle: According refraction, curved material best, right angle refraction material loss is large. 3. Space: the magnetic field lines in the air as cell phone signals, the need for space to be refracted. Flashlight bulbs completely wrapped in the pot as bulbs, use effects are not good, because there is a lot of light refraction are losses. How can I take advantage of the above principle, preferably magnetically enhanced effect, is seeking the best among many parameters, a lot of manufacturers are doing repeated experiments, such as Cathay Pacific magnet factory in Xi'an sided magnetic treatment to enhance the best result of 50% so that packaging bags and other areas will greatly reduce production costs and saving material. 5.7 NdFeB (Neodymium magnet) also known as NdFeB magnets, of the formula Nd2Fe14B, the permanent magnet is an artificial, so far the strongest permanent magnets having a magnetic force. Known as magnetic king, we have extremely high magnetic its biggest energy product (BHmax) higher than the ferrite (Ferrite) more than 10 times. Machining performance itself is also very good. Operating temperature up to 200 degrees Celsius. And its hard, stable performance, good price, so its application is extremely broad. But because of its chemical activity is very strong, it must deal with its surface coating. (E.g. plating Zn, Ni, electrophoresis, passivation, etc.). Neodymium magnets are Sumitomo Special Metals Corporation Sagawa, who live invented in 1982, known by its chemical formula, etc. which is mainly composed of neodymium, iron and boron chemical element of the composition. In many areas it is possible to replace the traditional ferrite magnets, alnico and samarium cobalt magnets such as motors, equipment and instrumentation, automotive, petrochemical industry and magnetic health-care products. We can produce a variety of shapes: such as disc magnets, ring magnets, rectangle magnets, arc magnets, and other shapes of magnets. Neodymium magnet having a strong magnetic field has been widely used in electronic products, such as hard drives, mobile phones, headsets, and so on. Also known as the main ingredient magnet magnet refers to the presence of magnetic objects or materials in and around their own internal, is divided into two major categories of natural and man-made. Artificial magnets usually made of metal alloys having a ferromagnetic. It can be divided into a "permanent magnet" and "non-permanent magnet," or "hard magnetic" and "soft." Natural magnet main ingredients: iron oxide, the chemical formula Fe3O4, often referred to as "the magnetic iron oxide." Magnetic black crystals. Compound ferrous oxide and iron oxide can be seen as. Because the iron oxide crystals in the presence of two different valence states of ions, a third of Fe2 +, two-thirds of Fe3 +, is a complex compound. It is insoluble in water, it can not react with water. And an acid, alkali-insoluble. The main system for primer and topcoat, magnetic materials for the electronics industry, but also for anti-rust agent construction industry
