![]() They are however, more sensitive to temperature. What are the main characteristics of neodymium magnets? Neodymium magnets are far less subject to cracking & chipping and less costly than other rare-earth magnetic material such as Samarium Cobalt ("SmCo"). ![]() How long do neodymium magnets last? Neodymium magnets will likely lose less than approximately 1% of their flux density over a 10-year period if their physical properties remain intact, and they are not subjected to demagnetizing influences (such as high-temperatures, opposing magnetic fields, radiation etc.). This can potentially lead to a lower overall cost, as the size of the entire device can shrink. Although they are more costly than ceramic magnets, strong neodymium magnets pack a powerful punch! A primary benefit is that you can use a smaller sized NdFeB magnet to achieve the same objective as a larger, less expensive magnet. Why are neodymium magnets so strong? Neodymium magnets are considered strong because they have a high saturation magnetization and resist demagnetization. ![]() They are also referred to as “NdFeB”, “Neo” or “NIB” magnets, as they are composed mainly of Neodymium (Nd), Iron (Fe) and Boron (B). What is a neodymium magnet? Neodymium magnets are strong permanent magnets, and part of the Rare-Earth magnet family.
