Sintered NdFeB magnets are brittle materials, and their mechanical properties are hard and brittle, that is, high strength and low toughness, and there is almost no plastic deformation before fracture, that is, it breaks in the elastic deformation stage.

The mechanical properties of materials generally include strength, hardness, plasticity and toughness, and these mechanical properties parameters have different physical meanings.

The global superconducting magnets market is expected to witness rapid growth over the next seven years owing to increasing demand from various end-use industries

When it comes to magnetic materials, we have to talk about "magnetism" first. Experiments have shown that any substance can be magnetized to varying degrees in an external magnetic field. According to the characteristics exhibited by substances in an external magnetic field, substances can be divided into five categories: paramagnetic substances, diamagnetic substances, ferromagnetic substances, ferrimagnetic substances, and antiferromagnetic substances.

In today's society, children's education and intellectual development have received unprecedented attention. Parents and educators are seeking various methods to promote the comprehensive development of children. Puzzle toys, as a tool that combines education and entertainment, have received widespread attention. Among them, puzzle magnets, as an emerging puzzle toy, have gradually become an important component of children's education due to their unique characteristics and diverse gameplay. This article will explore the positive effects of educational magnets on children's intellectual development

With the thawing of sintered NdFeB patented technologies in Japan, Germany, and the European Union, and the concerted efforts of major sintering manufacturers in China, the performance of sintered NdFeB products has been greatly improved. As a high-tech application field, its comprehensive performance has been continuously improved, The requirements for the surface treatment of its sintered NdFeB have also been greatly increased, and traditional treatment methods have been unable to meet the requirements of the progress of the industrial chain. The University of Electronic Science and Technology of China, Sichuan University, Jiaotong University, Rui Shilai and other major scientific research institutions in China, from microscopic molecules Starting with the structure, essentially perfecting the principle of surface treatment and the development of industrial application processes, after 4 years of hard work, we have achieved key technical developments.

As the strongest magnet currently known, neodymium magnets have the characteristics of high remanence and high coercivity, and are widely used in motors, horns, wind generators, new energy automobile motors, medical equipment, electronic appliances and other fields.

There are many types of magnets, and each type of magnet has a different grade, so how to choose the right magnet

The calculation results of the calculation models found online vary greatly, which one is more accurate? Is there a corresponding relationship between surface magnetism and residual magnetism?

Sintered neodymium iron boron permanent magnets are the highest magnetic materials discovered so far, widely used in various fields such as wind power generation, new energy vehicles, maglev trains, intelligent robots, etc. Sintered neodymium iron boron magnets use powder metallurgy technology, and the raw materials contain highly active rare earth elements, which deteriorate their corrosion resistance in high-temperature and high humidity environments, greatly limiting their use in various complex working conditions. This places higher demands on the comprehensive performance of neodymium iron boron magnets in practical applications.

Sintered neodymium iron boron permanent magnet materials have excellent performance and are widely used in fields such as automobiles, home appliances, wind power, and consumer electronics. They are currently the most important type of permanent magnet material in the market. In recent years, with the booming development of the electronic information industry, wind power, and new energy vehicles, the demand for neodymium iron boron has been increasing, and the annual output of sintered neodymium iron boron has gradually increased. During the production process of sintering neodymium iron boron, a large amount of production waste is generated. At the same time, more and more electromechanical equipment containing neodymium iron boron magnets are being scrapped, resulting in a large amount of neodymium iron boron waste. The rare earth element content in neodymium iron boron materials accounts for more than 30%, and rare earth resources are non renewable. Using economically effective methods to recycle valuable substances from neodymium iron boron waste can create certain economic value, save resources, and reduce environmental pollution.

Parylene is a new type of conformal coating material developed and applied by Union Carbide Co. in the mid-1960s in the United States. It is a polymer of para xylene, which can be classified into various types based on its molecular structure, such as N, C, D, F, HT, etc.

Halbach Array (Halbach permanent magnet) is a type of magnetic structure. In 1979, American scholar Klaus Halbach discovered this special permanent magnet structure during electron acceleration experiments and gradually improved it, eventually forming the so-called "Halbach" magnet. It is an approximate ideal structure in engineering, which uses the arrangement of special magnet units to enhance the field strength in the unit direction, with the goal of generating the strongest magnetic field with the minimum amount of magnets.
