Application of NdFeB Magnet in Various Fields

Update:04 Mar 2021

The strong magnetic field properties of magnets have led to their use in many modern technologies, as well as in the fields of medicine and dentistry. NdFeB magnets are a powerful type of magnet that has been the subject of recent research. This news provides a brief explanation of the definition, history, and characteristics of rare earth magnets. In addition, a broad overview of results obtained in studies performed to date on the effects of magnets, and NdFeB magnets in particular, on body systems, tissues, organs, diseases, and treatment is provided. Though they are used in the health sector in various diagnostic devices and as therapeutic tools, there is some potential for harmful effects, as well as the risk of an accident. The research is still insufficient; however, NdFeB magnets appear to hold great promise for both diagnostic and therapeutic purposes.

Neodymium is a chemical element that was discovered in 1885. This element has a silvery-white metallic color and belongs to the group of lanthanides, which is a subgroup of rare earth elements in the periodic table and rapidly oxidizes in the air. Lanthanides play important roles in new technological developments, such as wind turbines, electronic hybrid vehicles, and the defense industry.

Neodymium-iron-boron magnets were developed in the 1980s. Because it provides high magnetic force even in lesser amounts, it has been increasingly given a more prominent role in the manufacture of strong permanent magnets made up of rare earth elements. In the field of information technology, NdFeB magnets are particularly used in hard disc drives, mobile phones, video and audio systems of television.

NdFeB magnets are also commonly used in magnetic separators, filters, ionizers, in the production of on–off buttons, safety sector, and security systems. Grease filter producers use NdFeB magnets in metal separators to more effectively filter out the iron powder in oil. Additionally, they are beneficial in covering machines, cars with awning, and in the production of magnetic tool belts. They are also used in jewelry clips, identification badges, and in the production of baby strollers that are attached to carriers via magnets.

The health sector is another field where NdFeB magnets are incorporated in medical devices for example in magnetic resonance imaging devices to diagnose and treat chronic pain syndrome, arthritis, wound healing, insomnia, headache, and several other diseases due to their ability to generate a static magnetic field. An increase in their usage has been observed over the last decade. These magnets are thought to have a curing effect and are therefore sometimes called “magic magnets”.
