Njengoko itekhnoloji iqhubeka nokuhambela phambili, amandla angabonakaliyo adlala indima ebalulekileyo emva kwemifanekiso-imagnethi.Ezi zixhobo zinamandla ziguqule amashishini ukusuka kwi-electronics ukuya kumandla ahlaziyekayo.Phakathi kwemagnethi ezininzi ezikhoyo,Iimagnethi zeNdFeBukongamela, ukunika amandla angenakulinganiswa kunye nokuguquguquka.
Ke, zithini kanye kanye iimagnethi zeNdFeB?I-NdFeB imele i-neodymium iron boron kwaye yimagnethi yomhlaba enqabileyo eyenziwe ikakhulu yi-neodymium, intsimbi kunye neboron.Iimagnethi zomhlaba ezinqabileyo ziyaziwa ngeempawu zazo zemagneti ezibalaseleyo, zibenza babe yinxalenye ebalulekileyo kwizicelo ezahlukeneyo.
Ngenxa yokwakheka kwazo okwahlukileyo, iimagnethi ze-NdFeB zinamandla amangalisayo emagnethi adlula ezinye iimagnethi ezisisigxina.Amandla abo aphezulu abenza babe lolona khetho lokuqala kumashishini afuna izixhobo ezixineneyo kodwa ezinamandla zemagnethi.Ukusuka kwikhompyuter ukuya kwiimoto zombane,Iimagnethi zeNdFeBkwandisa ukusebenza kunye nokusebenza kakuhle.
Ngaphandle kobukhulu babo buncinci, iimagnethi zeNdFeB zidlala indima ebalulekileyo kwicandelo lamandla avuselelekayo.Zibalulekile kwiiinjini zomoya, ezivumela uguqulo lwamandla olusebenzayo ukusuka kumandla oomatshini ukuya kumandla ombane.Kwizithuthi zombane, iimagnethi zeNdFeB zisetyenziswa kwiimotor ezinamandla zombane ukuphucula isantya kunye nokusebenza ngokubanzi.
Ishishini le-aerospace nalo lixhamla kakhuluIimagnethi zeNdFeB.Zisetyenziswa kwizicelo ezahlukeneyo ezifana neenkqubo zesikhokelo, ii-activators kunye nezinzwa.Ubungakanani babo obuncinci, obudityaniswe namandla aphezulu emagnethi, bubenza bafanelekele indawo ezixineneyo.
Kwicandelo lezonyango,Iimagnethi zeNdFeBzibonakalise ukuba zinendima ebalulekileyo kwizixhobo zokuxilonga ezikumgangatho ophezulu ezifana noomatshini beMRI.Amandla emagnethi anamandla anceda ukuvelisa imifanekiso eneenkcukacha zomzimba womntu, ukunceda uxilongo kunye nokubeka iliso kwiimeko ezahlukeneyo.Ukongeza, zisetyenziselwa ukufakelwa kwezonyango, njenge-pacemakers, ukuququzelela ukusebenza okuchanekileyo.
Kuyafaneleka ukuba uqaphele ukuba ukhathalelo olukhethekileyo luyafuneka njengokoIimagnethi zeNdFeBzisemngciphekweni omkhulu wokubola.Faka i-coating efana ne-nickel, i-zinc okanye i-epoxy ukukhusela imagnethi kwizinto zokusingqongileyo.Ukongeza, iimagnethi zeNdFeB zomelele kakhulu kwaye zinokubeka umngcipheko wokhuseleko ukuba aziphathwa ngenkathalo.
Isishwankathelo, iimagnethi zeNdFeB ziguqule amashishini awohlukeneyo ngamandla awo aphezulu kunye noluhlu olubanzi lwezicelo.Ukusuka kumbane ukuya kumandla avuselelekayo kunye nezixhobo zonyango, ezi magnethi zomhlaba zinqabileyo ziyaqhubeka nokudlala indima ebalulekileyo ekunikeni amandla kwihlabathi lanamhlanje.Njengoko itekhnoloji ihambela phambili, sinokulindela ukuqhubela phambili ngakumbiNdFeB umazibutheiteknoloji, ukuvula amathuba amatsha kunye nokuphucula uluhlu olubanzi lwezicelo.
