NdFeB magnets NdFeB (Neodymium magnet) is also known as NdFeB magnets, and its formula is Nd2Fe14B, the permanent magnet is an artificial, so far has the strongest magnetic force of the permanent magnets. Neodymium magnets are Sumitomo Special Metals Corporation Sagawa, who live invented in 1982, known by its chemical formula, etc. mainly by neodymium, iron and boron chemical elements of the composition. In many areas it is possible to replace the traditional ferrite magnets, alnico magnets and samarium cobalt magnet such as a small electric motor, instrument and meter, auto industry, petrochemical industry and magnetic health products. Can produce a variety of shapes: such as disc magnets, ring magnets, rectangular magnets, arc-shaped magnets and other magnets. Neodymium magnets have a strong magnetic field has been widely used in electronic products, such as hard drives, mobile phones, headsets and more. Non-permanent magnet: a non-permanent magnet is heated to a certain temperature suddenly loses its magnetic properties, which is due to the large magnet arrangement consisting of "meta magnet" of from order to disorder caused; magnet loses its magnetism placed in a magnetic field , when the magnetization reaches a certain value, it is magnetized arrangement "Yuan magnet" in and from disorder to order. Artificial artificial magnet magnet: divided horseshoe magnet and bar magnet, is the most common of all life, which is popular horseshoe magnet. Sided magnet magnetic refers side, the other side of the weak magnetic solenoid magnet manufacturers, method is to use galvanized iron special handling package will face two-sided magnet, so one side of the magnetic shield will be wrapped, magnetic is refracted to the other side, the other side of the magnetic will be enhanced. If the occasion requires only one side of the magnetic, if the other side can cause damage or magnetic interference; some occasions, such as a magnet on the box you only need to have a magnetic side, the other side is optional, there is no use of magnetic, this will greatly reduce the use of single-sided magnetic magnetic material costs and savings. Sided magnet magnetic refraction as the satellite signal refraction pot or pan on flashlight lamp light refracting surfaces decision: 1 Material: choice of materials and thickness, and spacing of the magnet and the material has a close relationship. Pure iron is easy to push-pull solenoid magnetic flux leakage, after special treatment refraction will increase, but not 100% shielding materials developed, but the effect of different manufacturers make different materials.
