I-Bar Magnets ingahlukaniswa ibe ngolunye lwezinhlobo ezimbili: unomphela nowesikhashana. Omazilitiki baphakade bahlala besikhundla "esimweni"; okungukuthi, amandla kazibuthe awo ahlala esebenza futhi ekhona. Uzibuthe lwesikhashana kuyinto esetshenziswa kabi lapho isebenza ngamandla kazibuthe akhona. Mhlawumbe usebenzise uzibuthe ozodlala ngama-hairpins kanyoko osengumntwana. Khumbula ukuthi wakwazi kanjani ukusebenzisa i-hairpin enamathiselwe kuzibuthe ukucosha nge-hairpin yesibili? Lokho kungenxa yokuthi i-hairpin yokuqala yaba uzibuthe wesikhashana, ngenxa yamandla enkabu kazibuthe ezungeze. I-Electromagnets inguhlobo lwezinkathi zesikhashana eziba "ezisebenzayo" kuphela lapho ama-Electric's edlula kubo edala amandla kazibuthe.
Yini uMagnet we-Alnico?
Ama-magnets amaningi namuhla abizwa ngokuthi ama-magnets "Alnico", igama elisuselwa ezingxenyeni zensimbi ezenziwe ngalo: I-aluminium, nickel kanye ne-cobalt. I-Alnico Magnets imvamisa kungaba yi-bar- noma i-horseshoe ebunjiwe. Emagnanini ebhulukwe, izigxobo eziphambene nazo zisemaphethelweni ahlukile emgqonyeni, ngenkathi esezinhlanzweni zehhashi, izigxobo ziseduze kakhulu, emaphethelweni ehhashi. Ama-Bar Magnets nawo angakhiwa ngezinto zokwenziwa komhlaba ezingavamile - i-neodymium noma i-sadarium cobalt. Zombili lezi zigameko zebha elihlangene nezinhlobo ze-Bar Magnet ziyatholakala; Uhlobo olusetshenziswa ngokuvamile luncike ekusetshenzisweni kwesicelo kusetshenziswa yi-magnet.
Uzibuthe wami wephule ezimbili. Ngabe isasebenza?
Ngaphandle kokulahleka kwamandla kazibuthengi emaphethelweni aphukile, uzibuthe ophulwe kabili ngokujwayelekile ezokwakha ama-magnets amabili, ngalinye elizobe liqine njengezibuthe zoqobo zoqobo, ezingekho emthethweni.
Ukunquma izigxobo
Akuwona wonke ama-magnets aphawulwe ngo- "n" no- "s" ukucacisa izigxobo ezifanele. Ukunquma izigxobo zosizi uzibuthe we-bar, beka ikhampasi eduze kwesigcawu futhi ubuke inaliti; Isiphetho esivame ukubonakala esigxotsheni somhlaba esisenyakatho sisondela ukuze sikhombe esigxotsheni saseNingizimu ye-magnet. Lokhu kungenxa yokuthi uzibuthe usondele kakhulu kwikhampasi, ebangela ukuheha okunamandla kunamandla amakhulu omhlaba. Uma ungenayo ikhampasi, ungakwazi nokuntanta ibha esitsheni samanzi. UMagnet uzojikeleza kancane kancane kuze kube yilapho i-North Pole yayo ihambisana neNyakatho yangempela yomhlaba. Akunamanzi? Ungafinyelela umphumela ofanayo ngokumisa uzibuthe esikhungweni sawo ngentambo, ukuvumela ukunyakaza nokujikeleza ngokukhululeka.
Izilinganiso ze-Magnet
I-Bar Magnets ilinganiswe ngokuya ngezilinganiso ezintathu: Ukungeniswa kwemali okusele (BR), okubonisa amandla angaba yizibuthe; amandla aphezulu (Bhmax), alinganisa amandla amakhulu kazibuthe ezintokazi kazibuthe; Futhi amandla ahlanganisiwe (HC), atshela ukuthi kungaba nzima kangakanani ukuhlukanisa izibuthe.
Kukuphi amandla kazibuthe aqine kakhulu kuzibuthe?
Amandla kazibuthe we-bar magnethi aphezulu kakhulu noma agxile kakhulu kunoma yiliphi i-pole ukuphela futhi abuthakathaka maphakathi ne-magnet kanye nengxenye phakathi kwesigxobo nesikhungo sikaMagnet. Amandla ayalingana ngesigxobo. Uma ufinyelela ukugcwaliswa kwensimbi, zama lokhu: Beka uzibuthe wakho eflethini, ecacile. Manje fafaza imidwebo yensimbi ezungeze yona. Ukuhlunga kuzoqhubekela esimweni esihlinzeka ngokuboniswa okubonakalayo kwamandla kazibuthe: ama-filings azoba yi-densEST esigqeshini esisesigcawini lapho amandla kazibuthe aqine khona, asakazeka ngokwehlukana njengoba insimu iba buthaka.
Ukugcina Magnets Bar
Ukuze ugcine ama-magnets esebenza ngokusemandleni abo, kufanele kuthathwe ukunakekelwa ukuze kuqinisekiswe ukuthi igcinwe kahle.
Qikelela ukuthi ungavumeli ama-mass ahlanganiswe komunye nomunye; Futhi qaphela ukuthi ungavumi ama-marlots ukushayisana omunye nomunye lapho uzibeka kwisitoreji. Ukushayisana kungadala umonakalo kuzibuthe futhi kungadala ukulimala kweminwe eza phakathi kwama-magrets amabili aqine kakhulu ahehayo
Khetha isitsha esivaliwe ngenxa yama-magnets akho ukuvikela imfucumfucu yensimbi kusuka ekuhehwa kwama-magnets.
Gcina ama-magnets ekuhehelweni; Ngokuhamba kwesikhathi, amanye ama-magnets agcinwe ezikhundleni eziphindaphindayo angalahlekelwa amandla awo.
Gcina imantshi ye-Alnico "abagcini," amapuleti asetshenziselwa ukuxhuma izigxobo ze-Multiple Magnits; Abagcini basiza ukuvikela ama-magnets ukuthi angabikwa ngokuhamba kwesikhathi.
Gcina iziqukathi zokugcina kude namakhompyutha, ama-VCRS, amakhadi wesikweletu nanoma yimaphi amadivayisi noma amadivayisi aqukethe imichilo kazibuthe noma ama-microchips.
Futhi gcina ama-magthen aqinile endaweni etholakala kude kunoma iyiphi indawo engavakashelwa ngabantu abanama-pacemaker kusukela amasimu kazibuthe angaba namandla ngokwanele ukuba angezelwe i-pacemaker ukuthi ingasebenzi kahle.
