How Long Will a Neodymium Magnet Last?

Many people are relatively new to neodymium magnets, but when it comes to strong magnets, I believe most of us have heard of them. In fact, the strong magnet is another name for neodymium magnets. This kind of magnet is very common in the modern industry and has a super-strong magnetic force. Also, the neodymium magnets are usually very small and can be used in a wide variety of spaces and working environments. Then many people may have such a question: since neodymium magnets can be applied in different working environments, will it be demagnetized like other ordinary magnets? How long will a neodymium magnet last?

We all know that magnets are very widely used in our daily life, and the demand for magnets in the industry is also very large. However, there are magnets of various materials on the market today, and it is not easy to for one choose a magnet that suits him/her best. When choosing magnets, many people do not pay enough attention to the production process or types of magnets. As a result, problems of one kind or another will occur in the actual use of the magnets.

For example, some magnets do not have a long service life, while some cannot withstand high temperatures. But the neodymium magnet is produced by special process and material. It has the characteristics of small size, lightweight, strong magnetism, and long service life. So, how long will the magnetism of NdFeB magnets last in practice?

How long will a neodymium magnet last?

Neodymium magnet is a kind of permanent magnet based on the intermetallic compound Nd2Fe14B. The main components of neodymium magnet are neodymium (Nd), iron (Fe), and boron (B).

Among them, the rare earth element is mainly neodymium (Nd), but in order to obtain different properties, some rare earth metals such as dysprosium (Dy), praseodymium (Pr) can be used to replace neodymium. The iron can also be partially replaced by other metals such as cobalt (Co), aluminum (Al), etc. The boron content is small, but it plays an important role in the formation of tetragonal crystal structure intermetallic compounds, making the compound have high saturation magnetization, high uniaxial anisotropy, and high Curie temperature.

Neodymium magnets have a very high coercive force, and there will be no demagnetization and magnetic changes under the natural environment and general magnetic field conditions. Assuming under an appropriate environment, even after a long period of use, the magnetic performance of the magnet will not be greatly reduced. Therefore, in practical applications, we often ignore the influence of time on the magnetic performance of neodymium magnets.
