Kev tsim cov hlau nplaum
Raws li kev siv dav dav ntawm cov khoom sib nqus, cov hlau nplaum tau tsim ntau txoj hauv kev kom lawv tuaj yeem siv tau ntau txoj hauv kev. Ntawm no, kuv tab tom qhia cov npe nrov tshaj plaws thiab ntau txoj hauv kev uas tsim cov hlau nplaum ua tiav.
• Electromagnets:Raws li lub npe sawv cev, electromagnets yog cov hlau nplaum uas tuaj yeem tswj tau los ntawm kev tuav cov hluav taws xob tam sim no. Cov hlau nplaum no yog tsim los ntawm kev sib sau ib lub xaim (feem ntau yog ib co coil) nyob ib ncig ntawm ib qho khoom sib nqus. Thaum cov tam sim no dhau los ntawm cov hlau no nws yuav pab tsim kom muaj ib qho chaw sib nqus. Lub magnetic teb nyob twj ywm ntev npaum li qhov tam sim no ntws los ntawm cov hlau. Feem ntau, tooj liab hlau yog siv los tsim electromagnets vim tooj liab yog ib tug zoo conductor ntawm hluav taws xob.
• Ferromagnets:Cov hlau nplaum tsim los ntawm cov ntaub ntawv ferromagnetic yog hu ua ferromagnets. Cov hlau nplaum no yog tsim los ntawm cov khoom muaj zog xws li npib tsib xee, hlau, thiab cobalt. Cov ferromagnets raug rau cov hlau nplaum sab nraud uas muaj zog heev. Xws li raug pab ntxiv dag zog rau qhov sib nqus ntawm cov ntaub ntawv no uas ua rau lawv cov hlau nplaum ruaj khov. Cov hlau nplaum tas mus li yog cov uas tuaj yeem khaws lawv cov khoom sib nqus txawm tias lawv tsis tshwm sim los ntawm lwm lub zog xws li cov hlau nplaum lossis hluav taws xob tam sim no.
• ALNICO hlau nplaum:Alnico hlau nplaum yog tsim los ntawm kev sib txuas ntawm txhuas (AL), npib tsib xee (NI), thiab cobalt (CO). Qee zaum hlau kuj ntxiv rau hauv qhov sib tov los ua cov hlau nplaum no. Alnico yog cov hlau nplaum muaj zog tiag tiag uas tuaj yeem tsim kom muaj zog sib nqus zoo li piv rau cov hlau nplaum tsis tu ncua.
