The main accessories of MOGICS Light, with strong adsorption function, can replace ordinary magnets and iron. Even the cloth, glass or carton can be fixed by the function of double-sided magnetic suction. https://live.staticflickr.com/65535/49235761423_c474ebdf3a_o.jpg The material used is strong magnetic, N50 grade neodymium magnets are rare earth magnets, currently the strongest magnet in the world https://live.staticflickr.com/65535/49236233476_d0ccf736b5_o.jpg https://live.staticflickr.com/65535/49236460117_18b0465222_o.jpg https://live.staticflickr.com/65535/49236459847_fbcb588a7d_o.jpg Small knowledge of neodymium magnets: Magnetic strength is indicated by grades from N24 to N54, where N24 is the lowest strength and N54 is the strongest strength Neodymium magnet is also called NdFeB magnet. It is a tetragonal crystal formed by neodymium, iron and boron (Nd2Fe14B). In 1982, Masato Sagawa of Sumitomo Special Metals discovered neodymium magnets. The magnetic energy product (BHmax) of this magnet was greater than that of samarium-cobalt magnets, and it was the largest magnetic energy product in the world at that time. Later, Sumitomo Special Metals successfully developed the powder metallurgy process, and General Motors successfully developed the melt-spinning process, which can produce NdFeB magnets. This kind of magnet is the strongest permanent magnet and the rare earth magnet most commonly used today. NdFeB magnets are widely used in electronic products, such as hard disks, mobile phones, headphones, and battery-powered tools. In order to avoid corrosion damage, the surface of the permanent magnetic material needs to be protected during use, such as gold, nickel, zinc, tin plating, and epoxy coating on the surface.
