Isisombululo sobushushu obuphezulu be-demagnetization ye-NdFeb

Abahlobo abanolwazi oluthile ngoomazibuthe bayayazi loo ntoNdFeb Neodymium Magnetzibonwa ngokubanzi njengomsebenzi ophezulu kunye neemveliso zemagnethi ezinexabiso eliphantsi kushishino lwemagnethi ngoku.Amasimi amaninzi obuchwepheshe obuphezulu atyunjwe ukuba enze iinxalenye ezahlukeneyo, ezifana nomkhosi wokhuselo lwelizwe, iteknoloji yombane, izixhobo zonyango, izixhobo zombane kunye neminye imimandla ebandakanyekayo.Iingxaki ezingakumbi nangakumbi zinokufunyanwa, phakathi kwazo ukukhutshwa kweemagnethi kwe-ndfeb kwimagnethi enamandla. indawo yobushushu obuphezulu itsale ingqwalasela enkulu. 

Kutheni kunjaloNdFeb Iimagnethi eziZisigxinaukuwohloka kwiqondo lobushushu eliphezulu?

I-NdFeb degaussing kubushushu obuphezulu imiselwa yisakhiwo sayo somzimba.Intsimi kazibuthe inokuveliswa yimagnethi, kuba ii-electron 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 imagnethi yalapha iya kuphazamiseka, kunye ne-demagnetization.

Nangona kunjalo, ukuxhathisa ubushushu bemagnethi ye-NdFeb mhlawumbi ijikeleze i-baidu, oko kukuthi, ngaphezu kwe-baidu iya 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 bayo bendawo yokusebenza, ukuze kuncitshiswe ukwenzeka demagnetization.

Okwesibini kukuphucula ukusebenza kweemveliso usebenzisa i-NdFeb imagnethi ukusuka kwimbono yezobuchwepheshe, ukwenzela ukuba babe nesakhiwo sokushisa esingaphezulu kwaye abachatshazelwa lula kwindalo. 

Okwesithathu, unokukhetha izixhobo zokunyanzeliswa okuphezulu kunye nokuqokelela kwamandla afanayo.Ukuba akunjalo, kuya kufuneka uncame ukuqokelelwa kwamandla 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.
