NdFeB magineti, magineti epasi asingawanzo anoshandiswa zvakanyanya mumhando dzakasiyana siyana dzeindasitiri nekutengeserana nekuda kweakanakisa magineti maitiro.Aya magineti anozivikanwa nekuda kwesimba rawo repamusoro, kuramba demagnetization, uye mutengo wakaderera, zvichiita kuti ive sarudzo yakakurumbira yemhando dzakasiyana dzemagetsi, michina yekurapa, uye muchina.
Chimiro cheNdFeB maginetizvakaoma, asi ndiko kuoma uku ndiko kunovapa hunhu hwavo hwakasiyana.Aya magineti anogadzirwa kubva musanganiswa we neodymium, iron, uye boron, ine zvidiki zvezvimwe zvinhu zvinowedzerwa kuwedzera magineti yavo.Kiyi yesimba rayo remagineti yakasarudzika iri mukurongeka kwemaatomu mukati meiyo kristaro chimiro.
Chimiro chekristaro cheNdFeB maginetiitetragonal lattice umo neodymium neboron atomu zvinoumba mirairi mukati meiyo lattice chimiro uye maatomu esimbi anogara munzvimbo dziri pakati pematanho aya.Kurongeka kwakasiyana uku kwemaatomu kunoyananisa nguva dzemagineti emaatomu, zvichigadzira simba remagineti.
Kuwedzera kune yavo yakasarudzika crystal chimiro,NdFeB maginetianowanzo kugadzirwa mune akasiyana maumbirwo uye saizi, kusanganisira mashiti, madhisiki, uye mabhuroko, kuti aenderane nekushandisa kwakasiyana.Zvikuru sei,Chikamu Ndfeb maginetianoshandiswa zvakanyanya mukugadzira mota, majenareta, magineti separators uye magineti resonance imaging (MRI) michina nekuda kwesimba rawo remagineti uye kugadzikana.
Muchidimbu, chimiro cheNdFeB magineti chinhu chakakosha mune yavo yakanaka magineti zvimiro.Iyo tetragonal lattice, yakasanganiswa neiyo chaiyo kurongeka kweneodymium, iron uye boron maatomu, inobvumira magineti aya kuratidza yakakwira magineti simba uye kuramba kune demagnetization. Chikamu Ndfeb magineti, kunyanya, inhengo inokosha mune zvakasiyana-siyana zvemabhizimisi uye zvekutengeserana zvinoda masimba ane simba uye akagadzikana magineti.
