NdFeB permanent magnets are divided into sintered NdFeB and bonded NdFeB magnets, and also include strong ndfeb magnet. Bonded NdFeB has magnetism in all directions and is corrosion resistant; while sintered NdFeB is easily corroded, and the surface needs to be plated. Generally, there are galvanized, nickel, environmentally friendly zinc, environmentally friendly nickel, nickel copper nickel, environmentally friendly nickel copper nickel, etc. Sintered NdFeB is generally divided into axial magnetization and radial magnetization, depending on the required working surface.
NdFeB permanent magnets have excellent magnetic properties and are widely used in electronics, electrical machinery, medical equipment, toys, packaging, hardware machinery, aerospace and other fields. The more common ones are permanent magnet motors, speakers, magnetic separators, and computer disks. Drivers, magnetic resonance imaging equipment, meters, etc.
NdFeB permanent magnets are high-tech materials for the National 863 Project. What he can generate is a biomagnetic field that simulates the characteristics of the human body's magnetic field, with stable performance! Acting on the human body can correct the human body’s own magnetic field, and by enhancing the bio-electromagnetic energy of the human body’s meridians, massage many acupoints on the human body and promote the movement of the meridians, so as to activate the meridians, increase the brain’s blood supply and oxygen, and promote hair follicle regeneration and recovery. Reduce the excitability of peripheral nerves in the cerebral cortex, and produce the effects of promoting bone and joint tissue metabolism, hypnosis, analgesia, sedation, blood circulation and eliminating anxiety. At present, it is commonly used in the domestic medical industry to treat chronic bone and joint diseases such as hair loss, insomnia, neurasthenia, cervical spondylosis, frozen shoulder, lumbar muscle strain, and lumbar disc herniation.
