Can rare earth permanent magnet material NdFeB cause harm to human body
views, Updated: July 21, 2021
According to the classical electromagnetic theory, only the changing electromagnetic field can produce radiation; The higher the frequency, the more radiation. Normal alternating current frequency is 220 Hertz. NdFeB produces a static magnetic field, which does not produce electromagnetic radiation.
NdFeB, a rare earth permanent magnet material, can produce a strong static magnetic field: the effect of static magnetic field on the human body, there is no clear conclusion in the scientific community. At present a lot of data propagandize magnetic field is beneficial to human body, there are a lot of magnetic therapy instruments, these, do not have clear conclusion truly from science. Strong magnetic fields may have an effect on the human body, but scientific data is also lacking. Besides, the magnetic field produced by NdFeB and other magnets attenuates quickly. Generally, the magnetic field is very weak 5-10cm away from the magnet, and it will not harm the human body.
