Iimagnethi zebha zinokuhlelwa zibe lunye lweentlobo ezimbini: isigxina kunye neyethutyana.Iimagnethi ezisisigxina zihlala zikwindawo “ekuyo”;oko kukuthi, intsimi yabo yamagnetic ihlala isebenza kwaye ikhona.Umazibuthe wexeshana yinto ethi yenziwe nguzibuthe xa isenziwa ngumhlaba okhoyo.Mhlawumbi wawusebenzisa umazibuthe xa wawudlala ngeentsimbi zikamama wakho usengumntwana.Khumbula indlela oye wakwazi ngayo ukusebenzisa i-hairpin eqhotyoshelwe kwimagnethi ukuze uthabathe i-hairpin yesibini?Kungenxa yokuba i-hairpin yokuqala yaba yimagnethi yethutyana, ngenxa yamandla ombane ojikelezayo.Iimagnethi luhlobo lwemagnethi yethutyana ethi ibe “isebenzayo” kuphela xa umsinga wombane udlula kuwo usenza umhlaba wemagnethi.
Yintoni i-Alnico Magnet?
Iimagnethi ezininzi namhlanje zibizwa ngokuba ziimagnethi “zealnico”, igama elithatyathwe kumalungu ealloyi zentsimbi ezenziwe ngawo: iAluminum, iNIckel kunye neCObalt.Iimagnethi zeAlnico zihlala zimile okwebhari okanye isihlangu sehashe.Kwimagnethi yebar, izibonda ezichaseneyo zibekwe kwiindawo ezichaseneyo zebar, ngelixa kwimagnethi yehashe, izibonda zibekwe ngokusondeleyo kunye, eziphelweni zehashe.Iimagnethi zebha zinokuqulunqwa ngezinto ezinqabileyo zomhlaba - i-neodymium okanye i-samarium cobalt.Zombini iimagnethi zebar ezinamacala kunye neentlobo zemagnethi ezingqukuva ziyafumaneka;uhlobo olusetyenziswayo luxhomekeke kwisicelo apho imagnethi isetyenziselwa yona.
Imagnethi yam yaqhawuka kubini.Ngaba Isasebenza?
Ngaphandle kwelahleko yemagnethi enokwenzeka ecaleni komphetho owaphukileyo, umazibuthe oqhawuke kubini ngokubanzi uya kwenza oomazibuthe ababini, enye nenye iya kuba sisiqingatha somelele njengemagnethi yoqobo, engaqhawukanga.
Izibonda zokumisela
Ayizizo zonke iimagnethi eziphawulwe ngo-“N” kunye no-“S” ukubonisa iipali ezifanelekileyo.Ukumisela iipali ze-bar-type umazibuthe, beka ikhampasi kufutshane nemagnethi kwaye ujonge inaliti;Isiphelo esiqhele ukukhomba kwipali esemantla yoMhlaba siya kujika sijikeleze siqonde kwipali esemazantsi yemagnethi.Oku kungenxa yokuba umazibuthe usondele kakhulu kwikhampasi, ebangela umtsalane onamandla kunomhlaba wemagnethi womhlaba.Ukuba ngaba awunayo ikhampasi, unako kwakhona ukudada ibha kwisikhongozeli samanzi.Umazibuthe uya kujikeleza kancinci de ipali yayo yasemantla ilungelelaniswe nomntla wokwenene woMhlaba.Akukho manzi?Unokufezekisa umphumo ofanayo ngokumisa umazibuthe kwiziko layo ngomtya, ukuvumela ukuba uhambe kwaye ujikeleze ngokukhululekileyo.
Imilinganiselo yemagnethi
Umazibuthe weBar ulinganiswe ngokwemilinganiselo emithathu: intsalela yokwenziwa kwemagnethi (Br), ebonisa amandla anokubakho umazibuthe;ubuninzi bamandla (BHmax), obulinganisa amandla ombane wemagnethi egcweleyo;kunye ne-coercive force (Hc), echaza ukuba kunokuba nzima kangakanani ukwenza imagnethi ingasebenzi kakuhle.
Uphi aMagnetic Force Owomeleleyo Kwimagnethi?
Amandla kazibuthe wemagnethi yebar yeyona iphezulu okanye eyona igxile kuyo nayiphi na isiphelo sepali kwaye buthathaka kumbindi wemagnethi kunye nesiqingatha phakathi kwepali kunye nombindi wemagnethi.Amandla ayalingana nakweyiphi na ipali.Ukuba unokufikelela kwiifayile zentsimbi, zama oku: Beka umazibuthe wakho kwindawo ethe tyaba, ecacileyo.Ngoku fafaza iifayili zentsimbi ngeenxa zonke.Iifayili ziya kuhamba ziye kwindawo ebonisa umboniso obonakalayo wamandla umazibuthe wakho: iifayili ziya kuxinene nakweyiphi na ipali apho amandla kazibuthe omelele, asasazeke ngokwahlukeneyo njengoko intsimi isiba buthathaka.
Ukugcina iimagnethi zeBar
Ukugcina iimagnethi zisebenza ngokusemandleni abo, kufuneka kuthathelwe ingqalelo ukuqinisekisa ukuba zigcinwe ngokufanelekileyo.
Lumka ungavumeli iimagnethi zincamathele omnye komnye;kananjalo ulumkele ukuba ungavumeli iimagnethi ukuba zingqubane xa uzibeke kwindawo yokugcina.Ukungqubana kunokubangela umonakalo kwimagnethi kwaye kunokubangela ukwenzakala kwiminwe ephakathi kweemagnethi ezimbini ezinamandla kakhulu.
Khetha isikhongozeli esivaliweyo semagnethi ukunqanda ubutyobo besinyithi ekubeni butsaleleke kwimagnethi.
Gcina oomazibuthe kwiindawo ezitsala umdla;ngokuhamba kwexesha, ezinye iimagnethi ezigcinwe kwiindawo zokugxotha zinokuphelelwa ngamandla.
Gcina iimagnethi zealnico kunye "nabagcini," iipleyiti ezisetyenziselwa ukudibanisa iipali zeemagnethi ezininzi;abagcini banceda ukuthintela iimagnethi ekubeni zingasebenzi ngokwemagnethi ekuhambeni kwexesha.
Gcina izikhongozeli zogcino zikude kwiikhompyuter, iiVCR, amakhadi okuthenga ngetyala kunye nazo naziphi na izixhobo okanye imidiya equlathe izicuku zemagnethi okanye iimicrochips.
Kwakhona gcina imagnethi eyomeleleyo kwindawo ekude kuyo nayiphi na indawo enokuthi ihanjelwe ngabantu abanezincedisi-ntliziyo kuba iimagnethi zinokuba namandla ngokwaneleyo ukwenza isincedisi-ntliziyo singasebenzi.
