Gaar ahaan Neodymium Giraanta Magnet ee Matoorka iyo Afhayeenka
Sharaxaada Alaabta
Neodymium waa bir ductile ah oo la dareemi karoNeodymium si xoog leh ayaa paramagnetic ah.Codsiga ugu weyn ee neodymium wuxuu ku jiraa magnets joogto ah oo xoog-sare leh oo ku saleysan Nd2Fe14B kuwaas oo loo isticmaalo matoorrada korantada ee waxqabadka sarreeya iyo koronto-dhaliyeyaasha, iyo sidoo kale magnets-ka spindle-ka ee darawallada adag ee kombiyuutarka iyo marawaxadaha dabaysha.Magnets Neodymium waxaa laga heli karaa noocyo kala duwan oo qaabab, cabbirro iyo darajooyin ah. Magnet-ka giraanta waa sida saxanadaha ama dhululubada, laakiin leh dalool dhexe.
Garaac NdFeB Astaamaha Magnet
1. Heerkulka shaqada oo sarreeya
Magnet-ka giraanta N48H neodymium waxay leeyihiin iska caabin heerkul aad u wanaagsan.Taxanaha NH ee magnets-ka ndFeB, heerkulka ugu sarreeya ee shaqeyn wuxuu gaari karaa 120 ℃.

3. Dahaarka / Duubista
Ikhtiyaarada: Ni-Cu-Ni, Zinc (Zn) , Epoxy Black, Rubber, Gold, Silver, iwm.
4. Jihada magnetic
Magnets giraanta waxaa lagu qeexaa saddex cabbir: Dhexroorka dibadda (OD), Dhexroorka Gudaha (ID), iyo Dhererka (H).
Noocyada jihooyinka birlabeedka ee giraanta giraantu waa axially magnetized, diametrically magnetized, radially magnetized, iyo axially magnetized.
