What is a neodymium magnet used for ?
Publish Time: 2020-08-27 Origin: Site
Neodymium permanent magnet(NdFeb magnets), which are currently the most commercially available magnets, are known as Magnet King. They have the characteristics of small size, light weight and strong magnetism, and are the magnets with the best performance-to-price ratio so far. With extremely high magnetic properties, its maximum magnetic energy product (BHmax) is more than 10 times higher than that of ferrite. (BH) max of neodymium magnets can easily reaches 30 MGOe and even goes up to 52 MGOe.Its own machining performance is also quite good. The operating temperature can reach up to 200 degrees Celsius. Neodymium magnets can replace SmCo magnets in most cases, especially where the operating temperature is less than 80 degree Centigrade.Moreover, its hard texture, stable performance, and good cost performance, so its application is extremely wide. But because of its strong chemical activity, it must be coated on the surface. (Such as Zn, Ni, electrophoresis, passivation, etc.).
Basic knowledge of neodymium permanent magnet
neodymium permanent magnets can be divided into two types: bonded NdFeB magnets and sintered NdFeB magnets
It is estimated that in the next 20-30 years, it is impossible to replace neodymium permanent magnets with magnetic materials. The main raw materials for the production of NdFeB magnets are metal neodymium, pure iron, boron-iron alloy and other additives.
The core technology of the NdFeB magnet industry is mainly reflected in the manufacturing process, which is specifically reflected in the uniformity, consistency, processing quality, and coating quality of its products.
As a third-generation rare earth permanent magnet material, NdFeB magnets have a high performance-price ratio. They are widely used in energy, transportation, machinery, medical, IT, home appliances and other industries, especially with the knowledge economy represented by information technology The development of NdFeB has continuously brought new uses to the rare earth permanent magnet NdFeB industry and other functional materials, which has brought a broader market prospect for the NdFeB industry.
neodymium magnets in medical applications
Neodymium iron boron magnet can produce a kind of biological magnetic field that simulates the characteristics of human 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, promote the movement of the meridians, so as to achieve the passage of the meridians, increase the brain’s blood supply and oxygen, reduce the excitability of the peripheral nerves of the cerebral cortex, and promote bone The effect of joint tissue metabolism, hypnosis, analgesia, sedation, blood circulation and anxiety elimination. At present, it is commonly used to treat chronic diseases of bones and joints such as insomnia, neurasthenia, cervical spondylosis, frozen shoulder, and symptoms such as pain and numbness caused by these diseases.
The application range of NdFeB magnet is as follows
Electroacoustic field: speakers, receivers, microphones, alarms, stage audio, car audio, etc.
Electronic appliances: permanent magnet mechanism vacuum circuit breaker, magnetic holding relay, watt-hour meter, water meter, sound meter, reed switch, sensor, etc.
Motor field: VCM, CDDVD-ROM, generators, motors, servo motors, micro motors, motors, vibration motors, etc.
Mechanical equipment: magnetic separation, magnetic separator, magnetic crane, magnetic machinery, etc.
Medical and health care: nuclear magnetic resonance instrument, medical equipment, magnetic therapy health products, magnetized fuel economizer, etc.
Other industries: magnetized anti-wax device, pipe descaling device, magnetic fixture, automatic mahjong machine, magnetic lock, door and window magnet, luggage magnet, leather magnet, toy magnet, tool magnet, craft gift packaging, etc.
Neodymium magnets are the most powerful magnet developed so far and due to this reason and its affordable cost, neodymium magnets are revolutionizing magnetic products across all the industries. No matter where you go, you can always find neodymium magnets in action.
