Iimagnethi zeNdFeB, ziimagnethi zomhlaba ezinqabileyo ezisetyenziswa ngokubanzi kwiinkqubo ezahlukeneyo zoshishino kunye nezorhwebo ngenxa yeempawu zabo ezintle zemagneti.Ezi magnethi zaziwa ngamandla azo aphezulu, ukuxhathisa kwi-demagnetization, kunye nexabiso eliphantsi, nto leyo ebenza babe lukhetho oludumileyo lwezixhobo zombane ezahlukeneyo, izixhobo zonyango kunye noomatshini.
Ubume beIimagnethi zeNdFeBintsonkothile kakhulu, kodwa kobu bubunzima obubanika iimpawu zabo ezizodwa.Ezi magnethi zenziwe ngokudityaniswa kwe-neodymium, i-iron, kunye ne-boron, kunye nemilinganiselo emincinci yezinye izinto ezongeziweyo ukuphucula iimpawu zazo zemagneti.Isitshixo kumandla ayo akhethekileyo emagnethi silele kulungiselelo lweeathom ngaphakathi kwesakhiwo sekristale.
Ubume bekristale yeIimagnethi zeNdFeByileyithi ye-tetragonal apho i-neodymium kunye ne-athom ze-boron zenza umaleko ngaphakathi kwesakhiwo se-lattice kunye nee-athom zentsimbi zithatha izithuba phakathi kwezi maleko.Olu lungelelwano lukhethekileyo lweeathom lulungelelanisa amaxesha emagnethi eeathom, ludala imagnethi eyomeleleyo.
Ukongeza kubume bekristale obukhethekileyo,Iimagnethi zeNdFeBzidla ngokuveliswa kwiimilo ezahlukeneyo kunye nobukhulu, kubandakanywa amaphepha, iidiski, kunye neebhloko, ukuze zilungele izicelo ezahlukeneyo.Ukuthi ngqo,Inxalenye Ndfeb umazibuthezisetyenziswa ngokubanzi kwimveliso yeenjini, iijenereyitha, izahluli zemagnethi kunye noomatshini bokucinga ngemagnethi (MRI) ngenxa yamandla abo aphezulu kunye nokuzinza.
Isishwankathelo, ubume bemagnethi ye-NdFeB yeyona nto iphambili kwiipropathi zabo zemagneti ezigqwesileyo.Ileyithi ye-tetragonal, idityaniswe nolungiselelo oluchanekileyo lwe-neodymium, intsimbi kunye ne-athom ye-boron, ivumela ezi magnethi ukuba zibonise amandla amakhulu omagnetic kunye nokuxhathisa ukukhupha kazibuthe. Inxalenye Ndfeb umazibuthe, ngokukodwa, licandelo elixabisekileyo kwiintlobo ezahlukeneyo zezicelo zoshishino kunye nezorhwebo ezifuna iindawo ezinamandla kunye nezinzile zamagnetic.
