Ibyerekeranye na Magneti Bar - Imbaraga za Magnetique nuburyo bwo guhitamo

Imashini yumurongo irashobora gushyirwa mubwoko bubiri: burigihe kandi bwigihe gito.Imashini zihoraho zihora mumwanya wa "kuri";ni ukuvuga, imbaraga zabo za magnetique zihora zikora kandi zirahari.Imashini yigihe gito nigikoresho gihinduka magnet iyo ikozwe numurima uhari.Birashoboka ko wakoresheje magneti kugirango ukine umusatsi wa nyoko ukiri umwana.Wibuke uburyo washoboye gukoresha umusatsi wometse kuri magneti kugirango ufashe magnetiki gufata umusatsi wa kabiri?Ibyo biterwa nuko umusatsi wambere wabaye magnet yigihe gito, bitewe nimbaraga zumurima wa rukuruzi uzengurutse.Electromagnets ni ubwoko bwa magneti yigihe gito ihinduka "ikora" gusa mugihe amashanyarazi anyuze muri bo arema umurima wa rukuruzi.
Magnetiki ya Alnico ni iki?
Imashini nyinshi muri iki gihe zitwa "magnetiki" alnico, izina rikomoka ku bigize ibice bivangwa n'ibyuma bivamo: ALuminium, NIckel na CObalt.Imashini ya Alnico mubisanzwe iba ari bar- cyangwa ifarashi.Mu rukuta rw'akabari, inkingi zinyuranye ziherereye ku mpande zinyuranye z'akabari, mu gihe mu rukuruzi rw'amafarashi, inkingi ziherereye hafi, ku mpera y'ifarashi.Imashini ya bar irashobora kandi kuba igizwe nibikoresho bidasanzwe byubutaka - neodymium cyangwa samarium cobalt.Byombi kuruhande rwibice bya magneti hamwe nuruziga ruzengurutse ubwoko burahari;ubwoko bukoreshwa mubisanzwe biterwa na porogaramu ikoreshwa na magneti.
Magnet yanjye Yacitsemo kabiri.Bizakomeza gukora?
Usibye gutakaza bimwe bya magnetisme kuruhande rwacitse, rukuruzi yacitsemo kabiri muri rusange izakora magnesi ebyiri, imwe murimwe izaba ifite kimwe cya kabiri gikomeye nkumwimerere, utavunitse.
Kugena Inkingi
Ntabwo magnesi zose zanditswemo "N" na "S" kugirango zerekane inkingi zijyanye.Kugirango umenye inkingi ya magneti yo mu bwoko bwa bar, shyira compas hafi ya magneti hanyuma urebe urushinge;iherezo risanzwe ryerekeza kuri pole y'amajyaruguru y'isi rizazunguruka ryerekeje kuri pole y'amajyepfo ya rukuruzi.Ni ukubera ko rukuruzi yegereye kompas, itera igikurura gikomeye kuruta isi ya rukuruzi.Niba udafite compas, urashobora kandi kureremba akabari mukibindi cyamazi.Magnet izagenda buhoro buhoro kugeza inkingi yayo yo mu majyaruguru ihujwe n’amajyaruguru yukuri yisi.Nta mazi?Urashobora kugera kubisubizo bimwe uhagarika magnet hagati yayo hamwe numugozi, ukayemerera kugenda no kuzunguruka mubuntu.
Urutonde rwa Magneti
Imashini zibari zapimwe ukurikije ibipimo bitatu: induction isigaye (Br), yerekana imbaraga zishoboka za rukuruzi;imbaraga ntarengwa (BHmax), ipima imbaraga za magneti yumurongo wibikoresho bya magneti byuzuye;n'imbaraga zo guhatira (Hc), ivuga uburyo bigoye gutandukanya magneti.
Nihehe imbaraga za rukuruzi zikomeye kuri Magneti?
Imbaraga za rukuruzi ya bar magneti ni ndende cyangwa yibanda cyane kumpera ya pole kandi igacika intege hagati ya rukuruzi no hagati hagati ya pole na centre ya magneti.Imbaraga zingana kuri pole.Niba ufite uburyo bwo kubona ibyuma, gerageza ibi: Shyira magnet yawe hejuru yubusa.Noneho kuminjagira ibyuma.Amadosiye azimuka mumwanya utanga kwerekana amashusho yimbaraga za magneti yawe: dosiye zizaba zuzuye kuri pole aho imbaraga za rukuruzi zikomeye, zikwirakwira nkuko umurima ucika intege.
Kubika Magneti
Kugirango magnesi ikore neza, igomba kwitonderwa kugirango ibike neza.
Witondere kureka magnesi zifatana hamwe;witondere kandi kutemerera magnesi kugongana mugihe ubishyize mububiko.Kugongana birashobora kwangiza magnet kandi birashobora no gukomeretsa intoki ziza hagati ya magnesi ebyiri zikomeye zikurura
Hitamo ikintu gifunze kuri magnesi yawe kugirango wirinde imyanda yumutare gukururwa na magnesi.
Ubike magnesi mukureshya imyanya;igihe kirenze, magnesi zimwe zibitswe mumwanya wo kwanga zishobora gutakaza imbaraga.
Bika magneti ya alnico hamwe n '“izamu,” amasahani akoreshwa mu guhuza inkingi za magneti nyinshi;abazamu bafasha gukumira magnesi kuba demagnetisime mugihe runaka.
Bika ibikoresho byabitswe kure ya mudasobwa, VCR, amakarita yinguzanyo nibikoresho byose cyangwa itangazamakuru ririmo imirongo ya magneti cyangwa microchips.
Komeza kandi magnesi zikomeye ahantu hitaruye ahantu hose hashobora gusurwa nabantu bafite pacemakers kuko imirima ya magneti ishobora kuba ikomeye kuburyo itera pacemaker gukora nabi.
