Iimagnethi ze-bar zinokuhlelwa kwenye yeentlobo ezimbini: zisisigxina nakwexeshana. Imagnethi esisigxina ihlala ikwi "kwi" kwisikhundla; Oko kukuthi, umhlaba wabo wemagneti uhlala usebenza kwaye ukhona. Imagnethi yethutyana yinto ebandakanya ibukhali xa isebenza yimagnethi esele ikho. Mhlawumbi usebenzise imagnethi yokudlala kunye neenwele zikanyoko njengomntwana. Khumbula ukuba wakwazi ukusebenzisa i-hairpin eqhotyoshelwe kwimagnethi ye-magneting thabatha i-rightin yesibini? Kungenxa yokuba i-hairpin yokuqala yaba yimagnethi yethutyana, enkosi kumandla e-magnetic ayijikelezileyo. I-electromagnets luhlobo lwemagnethi yethutyana ebaleka "isebenza" kuphela xa kudluliselwe kombane kuphela ngayo ukwenza intsimi yemagneti.
Yintoni i-alnido magnet?
Imagnethi ezininzi namhlanje zibizwa ngokuba "ziimazithi ze-Alnito", igama elivela kumacandelo entsimbi ye-Iron Alwalys olwenziwe kuyo: ialuminiyam, i-cobamt kunye ne-cobalt kunye ne-cobalt kunye ne-cobalt kunye ne-cobalt kunye ne-cobalt kunye ne-cobalt kunye ne-cobalt kunye ne-cobalt kunye ne-cobalt. I-Alnigo Magnets ihlala ikwi-bar- okanye ihashe. Kwi-Bar Magnet, izibonda ezichaseneyo zikwiziphelo ezichaseneyo zebar, ngelixa ikwindawo yehashe, izibonda zisondelelene, kwiziphelo zehashe. Iimagnethi ze-bar zinokuqulunqwa kwezixhobo ezinqabileyo zomhlaba - i-neodiyoum okanye i-samarium cobalt. Zombini iimagnethi ezinamacala athambileyo kunye neentlobo ze-barnet ze-gognet ziyafumaneka; Uhlobo olusetyenzisiweyo luhlala luxhomekeke kwisicelo esisetyenziswa nguMagnet.
Umazim wemagnet wam waqhekeza kabini. Izakusebenza?
Ngaphandle kokulahleka kwe-magnetism ecaleni komphetho ophukileyo, umazimatnet ophulwe ngawo amabini ngokubanzi uya kwenza iimagnethi ezimbini, nganye nganye iya kuba sisiqingatha soqobo, ungayithandi i-vernet yentsusa, engafezekanga.
Ukuchonga izibonda
Ayizizo zonke izinto zemazithi ziphawulwe ngo "N" no "s" ukuchaza izibonda. Ukuchonga izibonda ze-maginet yohlobo lwebhayithi, beka ikhampasi kufutshane nemagnet kwaye ubukele inaliti; Isiphelo esiqhelekileyo sikhomba kwi-Pole yoMhlaba esimantla iya kujijisa ukuya kwinqanaba ukuya kwi-South Pole yeMagnet. Kungenxa yokuba iMagnet isondele kakhulu kwikhampasi, ibangela umdlali onamandla kunendawo yomhlaba ye-magnetic. Ukuba awunayo ikhampasi, unokukhwela i-bar kwisitya samanzi. Imagnethi iya kujikeleza ngokuthe ngcembe de i-North Phole ihambelana nomhlaba kumhlaba wokwenene. Akukho manzi? Unokufikelela kwisiphumo esifanayo ngokumisa imagnethi kwiziko layo ngentambo, livumela ukuba lihambe kwaye lijikeleze ngokukhululekileyo.
I-Magnet Ratings
Iimagnethi ze-bar zibalwa ngokwemilinganiselo emithathu: I-Inder yokuPhambili (i-BR), ebonisa amandla anokubakho kwemagnet; Amandla aphezulu (i-BhMAX), elinganisa amandla ommandla wemagnethi ogcweleyo; kunye namandla okunyanzela (HC), nto leyo leyo ixelela indlela ekuya kuba nzima ngayo ukuxhasa iMagnet.
Iphi amandla ombane owomeleleyo kwimagnethi?
Amandla e-magneti ye-bar Magnet iphezulu okanye igxile kuyo nayiphi na i-Pole Store kwaye inobungozi embindini wemagnethi kwaye iphakathi kwengxowa kunye nendawo ye-goley. Amandla alingane nasiphi na isibonda. Ukuba unokufikelela kwiifilimu zentsimbi, zama oku: Beka imagnethi yakho kwindawo ethe tyaba, ecacileyo. Ngoku fafaza inyibilikisi yingqongqo. Iifilimu ziya kungena kwisikhundla esibonelela ngamandla abonakalayo amandla akho e-magnet: Iifilimu ziya kuba nzima kwi-pole apho amandla obuchule aqinileyo, esasasaza njengentsimi.
Ukugcina iimagnethi zebhari
Ukugcina amagqwirha asebenza okona kulungileyo, ukhathalelo kufuneka athathwe ukuqinisekisa ukuba bagcinwe ngokufanelekileyo.
Lumka ungazenzi amagqwirha axhonywe omnye komnye; Lumka ungavumeli i-magnets ukuze idibane xa ibeka kwindawo yokugcina. Ingqungqokelela inokubangela ukonakala kwimagnethi kwaye inokubangela ukonzakala kwiminwe eza phakathi kwamalungu amabini athatyathwayo
Khetha isikhongozeli esivaliweyo seemagnethi zakho ukuthintela inkunkuma ye-metallic ekubeni ungatsalwa kwiimagnethi.
Gcina iimagnethi ekutsaleni izikhundla; Ixesha elingaphezulu, ezinye iimagnethi ezigcinwe kwizikhundla eziguqukayo zinokuphulukana namandla abo.
Gcina iimazi ze-Alnito "ngoogcineza," iipleyiti ezisetyenziselwa ukudibanisa izibonda zemagnethi ezininzi; Abagcini banceda ukukhusela amagqwirha ekubeni baphethwe ngokuhamba kwexesha.
Gcina izikhongozeli zokugcina kude neekhompyuter, ii-VCRS, amakhadi okuthenga ngetyala kunye nazo naziphi na izixhobo okanye imithombo yeendaba eneziqwengana zemagneti okanye imicrochips.
Gcina iimazithi ezomeleleyo kwindawo ebisuka kuyo nayiphi na indawo ezinokutyelelwa ngabantu abanabantu abanamagqabindla oko amagqabi anokuba namandla ngokwaneleyo ukubangela ukungasebenzi kakuhle.
