Nd-Fe-B permanent magnet is a kind of Nd-Fe-B magnetic material, also known as the latest result of the development of rare earth permanent magnet materials. It is called “Magnet King” because of its excellent magnetic properties. NdFeB permanent magnet has extremely high magnetic energy product and coercivity.
At the same time, the advantages of high energy density make NdFeB permanent magnet materials widely used in modern industry, electronic technology and medical industry, which makes it possible to miniaturize, lightweight and thin instruments and meters, electroacoustic motors, magnetic separation magnetization, medical instruments, medical equipment and other equipment. Nd-Fe-B permanent magnet has the advantages of high cost performance and good mechanical properties;
The disadvantage is that the Curie temperature point is low, the temperature characteristics are poor, and it is easy to be powdered and corroded. It must be improved by adjusting its chemical composition and adopting surface treatment methods in order to meet the requirements of practical application.
NdFeB permanent magnets have excellent magnetic properties and are widely used in electronics, electric machinery, medical devices, toys, packaging, hardware machinery, aerospace and other fields. The more common ones are permanent magnet motors, speakers, magnetic separators, computer disk drives, magnetic resonance imaging equipment and instruments, etc.In addition, NdFeB permanent magnet is a high-tech material in the National 863 project, which has excellent medical effect.
It can produce a biological magnetic field that simulates the characteristics of human magnetic field, with stable performance! Acting on the human body, it can correct the deviation of the human body’s own magnetic field, massage many acupoints of the human body by enhancing the bioelectromagnetic energy of the human body’s meridians, and promote the operation of meridians and Qi, so as to dredge the meridians and activate the collaterals, increase the blood and oxygen supply to the brain, promote the regeneration and recovery of hair follicles, reduce the excitability of the terminal nerves of the cerebral cortex, and promote the metabolism of bone and joint tissues, hypnosis, analgesia, sedation, the effect of promoting blood circulation and eliminating anxiety.
At present, it is often used in the medical industry to treat chronic bone and joint diseases such as hair loss, insomnia, neurasthenia, cervical spondylosis, scapulohumeral periarthritis, lumbar muscle strain, lumbar disc herniation and so on.
