NdFeB is a very excellent magnetic material with extremely strong magnetic force. It is often used to make rare earth permanent magnets and precision equipment such as motors and electronic components in various high-tech applications. Its magnetic force will change with the increase of use time and changes in the external environment, but generally speaking, this change is very small and will not have much impact on its magnetic ability.

First of all, the magnetic force of NdFeB will change to a certain extent due to changes in external temperature. Its magnetic force gradually weakens with the increase of temperature and gradually increases with the decrease of temperature. This is because NdFeB material is a ferromagnetic material, and its magnetic moment will change due to the influence of temperature. However, with the development of modern science and technology and the optimization of technology, the temperature resistance of NdFeB material has been continuously improved. At present, NdFeB material that can operate stably in high temperature environment has also been successfully developed to meet the needs of different fields.

Secondly, the magnetic force of NdFeB will change to a certain extent due to the influence of external magnetic field. If NdFeB material is used in a strong magnetic field, due to the extremely high magnetic field strength, it will have a certain impact on its internal magnetic moment, weakening its magnetic force. However, this situation is not common in actual applications, because NdFeB material itself shows extremely strong magnetic field resistance and is suitable for various high magnetic field application scenarios.

Finally, the magnetic force of NdFeB will change due to the length of use. As the use time increases, the magnetic moment inside the NdFeB material will gradually weaken, and its magnetic force will also weaken. However, this change is very slow, and it usually takes several years of use to be clearly felt. Moreover, NdFeB material has extremely high stability and long life performance. Within the service life range, its magnetic force changes very little and will not affect the actual application effect.
