Baziwa ngamandla abo akhethekileyo kunye nokuguquguquka,iimagnethi ze-neodymiumziiimagnethi zomhlaba ezinqabileyoyenziwe ngealloyi ye-neodymium, intsimbi, kunye neboron. Ngenxa yeempawu zabo eziphezulu zemagneti, eziiimagnethi ezinamandlazisetyenziswa kuluhlu olubanzi lwezicelo ukusuka koomatshini boshishino ukuya kubathengi be-elektroniki. Nangona kunjalo, umbuzo oqhelekileyo uyavela: Ngaba iimagnethi ze-neodymium zinokuvulwa kwaye zicinywe?
Funda malungaiimagnethi ze-neodymium
Phambi kokuba ujonge ekujikeni nasekucimeni imagnethi, kuyafuneka ukuba uqonde ukuba zisebenza njani iimagnethi ze-neodymium. Ngokungafaniyo ne-electromagnets, enokuthi isebenze okanye ingasebenzi ngokulawula umsinga wombane, iimagnethi ze-neodymium zimagnethi ezisisigxina. Oku kuthetha ukuba abafuni mthombo wamandla wangaphandle ukugcina umhlaba wemagnethi. Amandla abo ngumphumo wokucwangciswa kwemimandla yamagnetic ngaphakathi kwezinto eziphathekayo, ezihlala zizinzile ngaphandle kokuba zichatshazelwa ziimeko ezinzima.
Ubume bemagnethi
Ukuze sibambe ingqikelelo yeemagnethi ezivula nokuvala, kufuneka siqale siqwalasele ubume bemagnethi ngokwayo. Iimagnethi ezisisigxina, kubandakanywa imagnethi ye-neodymium, zinendawo esisigxina yamagnetic. Le ntsimi yamagnetic ihlala "ivuliwe", inika amandla ombane angaguqukiyo. Ngokwahlukileyo, ii-electromagnets zinokuvulwa kwaye zicinywe ngokulawula umsinga wombane. Xa ikhoyo ngoku ihamba ngekhoyili yocingo ejikeleze i-core magnetic, intsimi yamagnetic yenziwa. Xa i-current iyeka, i-magnetic field iyanyamalala.
Ngaba iimagnethi zeneodymium zinokulawulwa?
Nangona iimagnethi ze-neodymium zingenakuvulwa kwaye zicinywe njengee-electromagnets, kukho iindlela zokulawula iziphumo zazo zemagneti. Enye indlela kukusebenzisa oomatshini ukwahlula okanye ukuhlanganisa imagnethi. Umzekelo, ukuba iimagnethi ezimbini ze-neodymium zibekwe kufutshane kunye, ziya kutsalelana okanye zigxothane ngokuxhomekeke kwindlela ezijongwe ngayo. Ngokususa ngokwasemzimbeni enye imagnethi isuka kwenye, "ucima" ngokufanelekileyo ukusebenzisana kwamagnetic.
Enye indlela ibandakanya ukusebenzisa imathiriyeli enokukhusela okanye yalathise kwakhona amandla emagnethi. Izixhobo zokukhusela imagnethi, ezifana nealloys ezinokungena kakhulu, zingasetyenziselwa ukubhloka okanye ukunciphisa amandla emagnethi kwiindawo ezithile. Le teknoloji inokudala indawo apho impembelelo yemagnethi ye-neodymium incitshisiwe, efana nokuyicima.
Usetyenziso kunye nokuTshintsha
Ukungakwazi ukuvula nokucima iimagnethi ze-neodymium ngokuthe ngqo kukhokelele kwizisombululo ezitsha kwiinkalo ezahlukeneyo. Umzekelo, kwimimandla yerobhothi kunye ne-automation, iinjineli zihlala zisebenzisa indibaniselwano yeemagnethi ezisisigxina kunye ne-electromagnets ukwenza iinkqubo ezinokulawulwa ngamandla. Le ndlela ye-hybrid isebenzisa izibonelelo zeemagnethi ezomeleleyo ezisisigxina ngelixa ibonelela ngokuguquguquka kokuvula okulawulwayo.
Kubathengi be-elektroniki, iimagnethi ze-neodymium zihlala zisetyenziswa kwizithethi, ii-headphones, kunye nee-hard drives. Ngelixa ezi zixhobo zixhomekeke kwiipropati zemagnethi ezisisigxina ze-neodymium, zihlala zidibaniswa nobunye ubuchwepheshe obuvumela isandi esilungisiweyo okanye ukugcinwa kwedatha, ngokufanelekileyo ukudala indawo elawulwayo kwimiphumo yamagnetic.
Ukuququmbela
Ukushwankathela, nangona imagnethi ye-neodymium ingenako ukuvulwa nokucima ngokwengqiqo yemveli, kukho iindlela ezininzi zokulawula iziphumo zabo zemagnethi. Ukuqonda iipropathi zezi magnethi zomeleleyo kunye nokusetyenziswa kwazo kunokukhokelela kwizisombululo ezitsha ezisebenzisa amandla azo ngelixa zibonelela ngokuguquguquka okufunwa bubuchwephesha bale mihla. Nokuba kungohlulwa ngoomatshini okanye ngokusetyenziswa kokhuselo lwemagnethi, ulawulo lweemagnethi ze-neodymium luyaqhubeka nokukhuthaza inkqubela phambili kuwo wonke amashishini amaninzi.
