Neodymium is a chemical element that was discovered in 1885. This element (atomic number 60) has a silver-white metallic color and belongs to the lanthanide element, which is a subset of the lanthanide elements (atomic number 57-71). The periodic table oxidizes rapidly in the air. Lanthanides play an important role in the development of new technologies, such as wind turbines, electronic hybrid vehicles, and the defense industry.
In nature, neodymium does not exist in the form of metals or mixed with other lanthanides, but can be used for general purposes after refining, and has been mainly mined in the United States, Brazil, India, Australia, Sri Lanka and China.
NdFeB magnets were developed by General Motors and Hitachi in the 1980s. Because it provides high magnetic force even in small amounts, its role is becoming more and more important in the manufacture of strong permanent magnets composed of rare earth elements. In the field of information technology, neodymium magnets are especially used in video and audio systems for hard disk drives, mobile phones, and televisions.
Neodymium magnets are also commonly used in the production of magnetic separators, filters, ionizers, switch buttons, safety departments and safety systems. Grease filter manufacturers use neodymium magnets in metal separators to filter out iron powder in oil more efficiently. In addition, they are also very useful in covering machines, cars with awnings, and in the production of magnetic tool belts. They are also used in the production of jewelry clips, identification badges, and strollers that are secured to the basket by magnets.
The health department is another area where neodymium magnets are integrated into medical equipment (such as magnetic resonance imaging equipment), which can diagnose and treat chronic pain syndrome, arthritis, wound healing, insomnia, headaches and several other diseases (due to Its ability to generate static electricity) magnetic field. In the past decade, people have observed an increase in their use . These magnets are considered to have a curing effect, so they are sometimes referred to as "magnets".
NASA uses neodymium magnets to maintain astronaut muscle tension during space flight.
Neodymium magnets have push-pull force and have been used as motion generating devices in orthodontic treatment. Molar distillation and lat expansion.
According to reports, the static magnetic field can stimulate bone formation through the differentiation or activation of osteoblasts.
