Abahlobo abanolwazi oluthile ngoomazibuthe bayayazi loo ntoNdFeb Neodymium Magnetzibonwa ngokubanzi njengomgangatho wokusebenza okuphezulu kunye neemveliso zemagnethi ezinexabiso eliphantsi kushishino lwemagnethi ngoku.Iindawo ezininzi zobugcisa obuphezulu ziye zayityumba ukuba yenze iindawo ezahlukeneyo, ezifana nomkhosi wokhuselo welizwe, iteknoloji ye-elektroniki, izixhobo zonyango, izixhobo zombane kunye neminye imimandla echaphazelekayo.Iingxaki ezininzi ngakumbi zinokufunyanwa, phakathi kwazo ukuchithwa kweemagnethi kwi-ndfeb yemagnethi enamandla. indawo yobushushu obuphezulu itsale ingqwalasela enkulu.
KutheniNdFeb Iimagnethi eziZisigxinaukuwohloka kwiqondo lobushushu eliphezulu?
I-NdFeb degaussing kubushushu obuphezulu imiselwa yisakhiwo sayo somzimba.Intsimi kazibuthe inokuveliswa yimagnethi, kuba iilekhtroni ezithwalwa yi-elektroni zijikeleza i-athomu kwicala elithile, elivelisa amandla athile omagnetic, kwaye emva koko ibe nefuthe. Kodwa ii-electron ezijikeleze ii-athom ngokuhambelana nolwalathiso olusekiweyo nazo zineemeko ezithile zobushushu, izinto ezahlukeneyo zemagneti zinokumelana nobushushu buhlukile, kwimeko yobushushu obuphezulu kakhulu, i-elektroniki iya kuphambuka kumzila wokuqala, isenzeko sesiphithiphithi, imathiriyeli kazibuthe ngeli xesha umhlaba wemagnethi wasekhaya uya kuphazamiseka, kunye ne-demagnetization.
Nangona kunjalo, ukuxhathisa ubushushu bemagnethi ye-NdFeb mhlawumbi ijikeleze i-baidu, oko kukuthi, ngaphezu kwe-baidu kuya kubonakala i-demagnetization phenomenon, ukuba ubushushu buphezulu, i-demagnetization phenomenon ibaluleke kakhulu.
Izisombululo ezininzi ezisebenzayo kubushushu obuphezulu be-demagnetization ye-NdFeb, iimagnethi ziyaboniswa.
Okokuqala, musa ukubeka imveliso umazibuthe NdFeb kwiqondo lobushushu eliphezulu kakhulu, ingakumbi ingqalelo ubushushu bayo ebalulekileyo, ezizezi, baidu, kwangethuba uhlengahlengiso ubushushu bendawo yokusebenza, ukuze kuncitshiswe ukwenzeka demagnetization.
Okwesibini kukuphucula ukusebenza kweemveliso usebenzisa i-NdFeb imagnethi ukusuka kwimbono yezobugcisa, ukwenzela ukuba babe nesakhiwo sokushisa esingaphezulu kwaye abachatshazelwa lula kwindalo.
Okwesithathu, unokukhetha izixhobo zokunyanzeliswa okuphezulu kunye nokuqokelela kwamandla afanayo.Ukuba akunjalo, kuya kufuneka uncame ukuqokelela amandla kamagnetic amancinci, kwaye ufumane izinto ezinokuqokelelwa kwamandla kazibuthe asezantsi kunye namandla aphezulu okunyanzeliswa, kodwa akusekho, unokukhetha i-samarium cobalt;ukubuyisela umva i-demagnetization, kuphelacobalt samariumiyafumaneka.
