IiMnethi zoMhlaba oNqabileyo

Samarium ayibe Magnet Ubume kunye neenkcukacha:

Umazibuthe weSamarium Cobalt (SmCo) ukwabizwa ngokuba ngumhlaba onqabileyo womazibuthe weCobalt. Ukumelana kwayo eliphezulu demagnetization kunye nozinzo lobushushu ezigqwesileyo kwenza SmCo lobushushu umazibuthe okanye Sm2Co17 umazibuthe ukusebenza ezinzile phantsi lobushushu eliphezulu ukuya ku-350 ° C. Ngokwesiqhelo akukho nto yokunxiba iyimfuneko. Ngenxa yoko umazibuthe weSmCo lukhetho lweprimiyamu yezixhobo zemagneti kwizicelo ezininzi zomsebenzi ophakamileyo njenge-aerospace, iimotorsports kunye namashishini ezithuthi.

Ukhuseleko lweMagnet:

Iimagnethi ezinqabileyo zomhlaba okanye iinkqubo zemagnethi zinamandla amakhulu, kungoko ke le migaqo ingezantsi yokhuseleko kufuneka yaziswa bonke abasebenzi abanokuyisebenzisa, bayiphathe, okanye bayicwangcise ukwenzela ukuthintela ukwenzakala okanye ukonakala kwiimagnethi.

Qinisekisa ukuba iimagnethi ezinqabileyo zomhlaba ziphantsi kolawulo xa zidibana kunye okanye izixhobo ze-ferromagnetic. Kubalulekile ukunxiba iiglasi zokukhusela kunye nezinye izixhobo ezifanelekileyo zokukhusela xa uphethe iimagnethi ezinkulu. Kukwacetyiswa ukunxiba iiglavu ukukhusela izandla zakho.

Gcina izinyithi ze-ferromagnetic kude nendawo yokusebenza. Mamela xa usebenza ngoomazibuthe. Sukusebenza ngoomazibuthe abakho umazibuthe ukuba uphantsi kwempembelelo yotywala, iziyobisi, okanye izinto ezilawulwayo.

Izixhobo ze-elektroniki ezibuthathaka kunye nezixhobo zinokutshintsha ulungelelwaniso okanye zonakaliswe ngumhlaba onamandla onamandla. Soloko ugcina iimagnethi ezenziwe ngomazibuthe umgama okhuselekileyo kude kwizixhobo ze-elektroniki ezibuthathaka. Isilumkiso esikhethekileyo kufuneka senziwe ukuba umntu unxibe i-pacemaker, kuba amandla amakhulu ombane angonakalisa i-elektroniki ngaphakathi kwe-pacemaker.

Ungaze uginye iimagnethi okanye ubeke oomazibuthe kufikelela ebantwaneni okanye kubantu abadala abaziingqondo. Ukuba iimagnethi ziginyiwe, qhagamshelana nogqirha ngokukhawuleza kunye / okanye ufune unyango lwangoko.

Iimagnethi zomhlaba ezinqabileyo zingenza iintlantsi ngokudibana ekuphatheni, ngakumbi xa zivunyelwe ukuba zichaphazele kunye. Ungaze uphathe iimagnethi zomhlaba ezinqabileyo kwimimoya eqhumayo kuba ukudanyaza kungayitshisa loo moya.

Umgubo womhlaba onqabileyo uyatsha; Ukutsha ngokukhawuleza kunokwenzeka xa umgubo womile. Ukuba usila, soloko umanzi uguqa iimagnethi ukunqanda ukutshiswa okuzenzekelayo kwesila yokusila. Ungaze womile. Qinisekisa ukuba unomoya owaneleyo xa usila iimagnethi.
