Honsen Magneticsiibiya birlabyada neodymium ee shatiga haysta.Magnet neodymium (sidoo kale loo yaqaan NdFeB NIB ama Neo magnet) oo ah nooca ugu badan ee la isticmaalo ee magnet naadirka dhulka, waa magnet joogto ah oo laga sameeyay daawaha neodymium, bir iyo boron si loo sameeyo qaabdhismeedka crystalline tetragonal Nd2Fe14B.Waxaa sameeyay 1982-kii General Motors iyo Sumitomo Special Metals, magnets neodymium waa nooca ugu xoogan ee magnetka joogtada ah ee ganacsi ahaan la heli karo.Waxay ku beddeleen noocyo kale oo magnet ah codsiyada badan ee alaabooyinka casriga ah ee u baahan magnets joogto ah oo xooggan, sida matoorada qalabka aan xadhiga lahayn, diskooga adag iyo qalabka magnetka.Ma hubtid in Neodymium uu yahay qalabka ugu fiican ee codsigaaga?Riix halkan sifada iyo isbarbardhigga codsiga ee dhammaan agabyada birlabeedka aan bixinno.
Neodymium wareegsan magnet joogto ah Sharaxaad
Qaab dhismeedka teetragonal Nd2Fe14B wuxuu leeyahay si gaar ah uniaxial magnetocrystalline anisotropy (HA ~ 7 teslas-magnetic field power H ee A/m iyo xilliga magnetic ee A.m2).Tani waxay siinaysaa xarunta awood ay ku yeelan karto qasbid sare (tusaale, iska caabin ah in la demagnetized).Xarunta ayaa sidoo kale leh magnetization saturation sare (Js ~ 1.6 T ama 16 kG) iyo sida caadiga ah 1.3 teslas. Sidaa darteed, sida cufnaanta tamarta ugu badan ee js2, marxaladdan magnetic waxay awood u leedahay kaydinta xaddi badan oo tamarta magnetic (BHmax ~ 512). kJ/m3 ama 64 MG·Oe) Gurigani aad buu uga sarreeyaa alliyada NdFeB marka loo eego samarium cobalt (SmCo) magnets, kuwaas oo ahaa nooca ugu horreeya ee birlab dhulka naadir ah oo ganacsi laga sameeyo.Ficil ahaan, sifooyinka birlabeedka neodymium magnets waxay ku xiran yihiin halabuurka daawaha, qaab-dhismeedka yar yar, iyo farsamada wax soo saarka ee la adeegsado.n45 neodymium magnet disc
