|
| Neodymium Magnet: Neodymium Magnet ni Neodymium Iron Boron magnet. Ni kizazi cha tatu nadra duniani na imekuwa magnet inauzwa tangu katikati -1980 's. Ni nadra kraftfullaste ardhi magnet leo possessing high nishati bidhaa kutoka 8MGOe kwa 52MGOe na Neodymium Iron Boron ina upinzani nzuri demagnetization nje kwa sababu ya mashamba yake high intrinsic Coercive Force (Hci). Hii upinzani inafanya Neodymium magneter an chaguo bora kwa electromechanical maombi. Pamoja na malighafi tele, NdFeB gharama kidogo. Pia wiani NdFeB bidhaa ni kuhusu 13% ndogo kuliko SmCo bidhaa, kwa sababu ni NdFeB magneter iliyokabiliwa na oxidation zaidi kuliko nyingine yoyote magnet alloy, hivyo kwa maombi mengi, mipako au plating ya magneter inapendekezwa.
