Samarium CobaltMignetIsishwankathelo kunye neNgcaciso:
Imagnethi yaseSamarium Cobalt (SmCo) ikwabizwa ngokuba yimagnethi yomhlaba enqabileyo yeCobalt. Ukuxhathisa kwayo okuphezulu kwi-demagnetization kunye nozinzo olubalaseleyo lobushushu kwenza i-SmCo yemagnethi yobushushu obuphezulu okanye imagnethi ye-Sm2Co17 isebenze ngokuzinzileyo phantsi kobushushu obuphezulu ukuya kuma-350 ° C. Ngokuqhelekileyo akukho ukutyabeka kuyimfuneko. Ke ngoko umazibuthe we-SmCo lukhetho lweprimiyamu lwemathiriyeli yemagnethi kwizicelo ezininzi zokusebenza eziphezulu ezifana ne-aerospace, i-motorsports kunye nemizi-mveliso yeemoto.

Ukhuseleko lwemagnethi:
Iimagnethi zomhlaba ezinqabileyo okanye iinkqubo zemagnethi zomelele ngokugqithisileyo, ngoko ke amanyathelo okhuseleko angezantsi kufuneka aziswe kwingqalelo yabo bonke abasebenzi abanokuthi basebenzise, baphathe, okanye basebenze ukuze baphephe ukwenzakala okanye ukonakala kwemagnethi.
Qinisekisa ukuba iimagnethi zomhlaba ezinqabileyo ziphantsi kolawulo xa zidibana enye kwenye okanye imathiriyeli yeferromagnetic. Kubalulekile ukunxiba iindondo zokhuseleko kunye nezinye izixhobo ezifanelekileyo zokukhusela xa uphethe iimagnethi ezinkulu. Ukunxiba iiglavu ukukhusela izandla zikabani nako kuyacetyiswa.
Gcina iintsimbi ze-ferromagnetic zikude nendawo yokusebenza. Qaphela xa usebenza ngeemagnethi. Sukusebenza ngemagnethi umazibuthe ukuba uphantsi kweempembelelo zotywala, iziyobisi, okanye izinto ezilawulwayo.
Izixhobo ze-elektroniki ezinovakalelo kunye nezixhobo zinokutshintsha ulungelelwaniso okanye zonakaliswe yimagnethi enamandla. Ngalo lonke ixesha gcina umazibuthe kumgama okhuselekileyo kude nezixhobo zombane ezibuthathaka. Kufuneka kulumke ngokukhethekileyo ukuba ubani unxibe isincedisi-ntliziyo, kuba amandla emagnethi anamandla anokonakalisa i-electronics engaphakathi kwi-pacemakers.
Ungaze uginye iimagnethi okanye ubeke iimagnethi kwindawo apho abantwana okanye abantu abadala abakhubazekileyo bengakwazi ukufikelela kuzo. Ukuba iimagnethi ziginyiwe, qhagamshelana nogqirha ngoko nangoko kwaye/okanye ufune unyango olukhawulezileyo.
Iimagnethi zomhlaba ezinqabileyo zinokudala iintlantsi ngokunxibelelana ekubambeni, ngakumbi xa zivunyelwe ukuba zichaphazele kunye. Ungaze uphathe iimagnethi zomhlaba ezinqabileyo kwiatmospheres eziqhumayo kuba i-sparking ingawutshisa loo moya.
Umgubo womhlaba onqabileyo uyatsha; ukutsha okuzenzekelayo kunokwenzeka xa umgubo womile. Ukuba uyasila, hlala umanzi sila iimagnethi ukunqanda ukutsha okuzenzekelayo kweswarf yokusila. Ungaze womise ucole. Qinisekisa ukuba unendawo yokuphefumla eyaneleyo xa usila iimagnethi. Sukuzama ukwenza iimagnethi zoomatshini usebenzisa izixhobo eziqhelekileyo, njengoko oku kunokuvelisa ukuqhekeka kunye nokuqhekeka. Hlala unxiba iindondo zokhuseleko.
Ngalo lonke ixesha gcina umgubo womhlaba onqabileyo okanye usila i-swarf kwizikhongozeli ezizaliswe ngamanzi okanye iatmospheres ezivaliweyo ezivaliweyo ukuthintela ukutsha okuzenzekelayo.
Hlala ulahla umgubo womhlaba onqabileyo ngenkathalo. Musa ukubeka engozini umlilo. Ukulahla imagnethi eyenziwe ngumazibuthe kufuneka kwenziwe ukuthintela ukwenzakala xa uphathwa.
