Ozibuthe bebha bangahlukaniswa babe munye wezinhlobo ezimbili: unomphela nowesikhashana.Ozibuthe baphakade bahlala besendaweni “evuliwe”;okungukuthi, insimu yabo kazibuthe ihlala isebenza futhi ikhona.Uzibuthe wesikhashana into eba nguzibuthe lapho yenziwa yinkundla kazibuthe ekhona.Mhlawumbe wawusebenzisa uzibuthe ukuze udlale ngezikhonkwane zikamama wakho useyingane.Khumbula ukuthi ukwazile kanjani ukusebenzisa iphinikhodi yezinwele exhunywe kuzibuthe ukuze uphakamise iphini lesibili lezinwele?Lokho kungenxa yokuthi i-hairpin yokuqala yaba uzibuthe wesikhashana, ngenxa yamandla kazibuthe ayizungezile.Ama-electromagnets awuhlobo lukazibuthe wesikhashana oluba “lusebenzayo” kuphela lapho ugesi udlula kuwo udala insimu kazibuthe.
Iyini I-Alnico Magnet?
Ozibuthe abaningi namuhla babizwa ngokuthi “ozibuthe be-alnico”, igama elisuselwe ezingxenyeni zengxubevange yensimbi abenziwa ngayo: I-aluminium, i-NIckel ne-CObalt.Ozibuthe be-Alnico ngokuvamile bamise okwe-bar- noma isicathulo samahhashi.Kuzibuthe webha, izigxobo eziphambanayo zitholakala emikhawulweni ehlukene yebha, kanti kuzibuthe zehhashi, izigxobo zitholakala eduze kakhulu, ekugcineni kwesicathulo sehhashi.Ozibuthe bebha bangase futhi bahlanganiswe ngezinto ezingavamile zomhlaba - i-neodymium noma i-samarium cobalt.Kokubili omazibuthe bamabha anezinhlangothi eziyisicaba kanye nezinhlobo zikazibuthe webha eliyindilinga ziyatholakala;uhlobo olusetshenziswayo ngokuvamile luncike kuhlelo olusetshenziswa uzibuthe.
Umazibuthe Wami Waphuka Kabili.Ingabe Isazosebenza?
Ngaphandle kokunye ukulahleka kukazibuthe onqenqemeni oluphukile, uzibuthe ophuke kabili ngokuvamile uzokwakha omazibuthe ababili, ngamunye ozoba namandla ngohhafu njengozibuthe wasekuqaleni, onganqamuki.
Ukunquma Izigxobo
Akubona bonke omazibuthe abamakwe ngo-“N” kanye “no-S” ukuze baveze izigxobo ezifanele.Ukuze unqume izigxobo ze-bar-type magnet, beka ikhampasi eduze nozibuthe futhi ubuke inaliti;isiphetho esivame ukukhomba esigxotsheni soMhlaba esisenyakatho sizoshwibeka sibheke esigxotsheni sikazibuthe esiseningizimu.Lokhu kungenxa yokuthi uzibuthe useduze kakhulu nekhampasi, okubangela ukukhanga okunamandla kunozibuthe woMhlaba.Uma ungenayo ikhampasi, ungakwazi futhi ukuntanta ibha esitsheni samanzi.Uzibuthe uzozungeza kancane kuze kube yilapho isigxobo saso sasenyakatho siqondana nenyakatho yangempela Yomhlaba.Awekho amanzi?Ungafinyelela umphumela ofanayo ngokumisa uzibuthe enkabeni yawo ngentambo, uyivumele ukuthi ihambe futhi ijikeleze ngokukhululekile.
Izilinganiso Zezibuthe
Ozibuthe bebha balinganiswa ngokwezilinganiso ezintathu: induction residual (Br), ebonisa amandla anamandla kazibuthe;amandla amakhulu (BHmax), akala amandla kazibuthe wezinto ezigcwele kazibuthe;namandla aphoqayo (Hc), atshela ukuthi kungaba nzima kangakanani ukukhipha uzibuthe.
Ikuphi I-Magnetic Force Eqine Kakhulu On A Magnet?
Amandla kazibuthe kazibuthe webha aphakeme kakhulu noma agxiliswe kakhulu kunoma iyiphi indawo ekupheleni kukazibuthe futhi aba buthakathaka phakathi nendawo kazibuthe kanye nohhafu phakathi kwesigxobo kanye nesikhungo sikazibuthe.Amandla ayalingana kuzo zombili izigxobo.Uma ukwazi ukufinyelela kumafayili ensimbi, zama lokhu: Beka uzibuthe wakho endaweni eyisicaba, ecacile.Manje fafaza amafayili ensimbi nxazonke.Amafayili azohamba aye endaweni enikeza ukuboniswa okubonakalayo kwamandla kazibuthe wakho: amafayili azominyene kunoma iyiphi indawo lapho amandla kazibuthe eqine kakhulu, asakazeke ngokuhlukana njengoba inkambu iba buthaka.
Ukugcina Omazibuthe Bebha
Ukuze ugcine omazibuthe besebenza kahle kakhulu, kufanele kuqikelelwe ukuthi bagcinwe ngendlela efanele.
Qaphela ukuthi ungavumeli omazibuthe banamathele komunye nomunye;futhi qaphela ukuthi ungavumeli omazibuthe bashayisane lapho bewabeka endaweni yokugcina.Ukushayisana kungabangela umonakalo kuzibuthe futhi kungabangela nokulimala eminwe efika phakathi kwezibuthe ezimbili ezinamandla kakhulu ezihehayo.
Khetha isitsha esivaliwe somazibuthe bakho ukuze uvimbele izinsalela zensimbi ukuthi zingaheheki kuzibuthe.
Gcina omazibuthe ezindaweni ezihehayo;ngokuhamba kwesikhathi, abanye omagnethi abagcinwe ezindaweni zokuxosha bangalahlekelwa amandla abo.
Gcina omazibuthe be-alnico “nabagcini,” amapuleti asetshenziselwa ukuxhuma izigxobo zikazibuthe abaningi;abagcini basiza ukuvimbela omazibuthe ukuthi bangabi nazibuthe ngokuhamba kwesikhathi.
Gcina iziqukathi zikude namakhompyutha, ama-VCR, amakhadi esikweletu nanoma imaphi amadivaysi noma imidiya equkethe amapheshana kazibuthe noma ama-microchips.
Futhi gcina ozibuthe abaqinile endaweni eqhelelene nanoma iyiphi indawo engase ihanjelwe abantu abanezinhliziyo ezishaya inhliziyo njengoba amandla kazibuthe angaba namandla ngokwanele ukuze abangele ukungasebenzi kahle kwenhliziyo yenhliziyo.
