Vim li cas cov hlau nplaum muaj zog muaj kev cuam tshuam loj rau yav tom ntej, thiab kev lag luam yuav muaj kev cuam tshuam dab tsi? Cia peb tsom xam cov hlau nplaum muaj zog los ntawm peb yam hauv qab no:
Kev tsom xam ntawm lub hauv paus ntsiab lus ntawm Magnetic Field Tsim ntawm Cov Hlau nplaum muaj zog
Cov hlau nplaum muaj zog muaj lub zog tshwj xeeb uas, zoo li hluav taws xob, tsis tuaj yeem pom lossis hnov los ntawm tib neeg hlau nplaum, tab sis nws lub zog muaj nyob txhua qhov chaw. Cov hlau nplaum tau yooj yim ua thiab lawv siv tau ntau heev. Txhua leej txhua tus paub tias muaj qhov gravitational teb ntawm qhov teeb meem. Zoo ib yam li cov hlau nplaum, nws yog ib qho chaw uas nyob ib ncig ntawm cov ncej hlau nplaum. Qhov luaj li cas ntawm cov magnetic teb tuaj yeem sawv cev los ntawm cov xov tooj ntawm cov kab hlau nplaum sib nqus. Lub denser cov magnetic teb kab, lub zog magnetic teb. Ntawm qhov tsis sib xws, qhov tsis muaj zog ntawm magnetic teb yog tias cov kab hlau nplaum sib nqus tsis sib xws. Cov hlau nplaum muaj zog, hauv kev txav, raug rau ib hom Lorentz quab yuam ntawm cov khoom siv hauv cov hlau nplaum. Lub zog sib nqus ntawm cov khoom siv hluav taws xob yog qhov txawv ntawm lub zog ntawm lub zog sib nqus ntawm Lorraine hlau nplaum nyob rau hauv sib txawv magnetic teb. Tesla yog ib chav thoob ntiaj teb tshwj xeeb siv los ntsuas qhov sib nqus flux ceev. Qhov ceev ntawm magnetic flux yog qhov tseem ceeb ntawm lub cev uas piav qhia nws cov magnetic teb, thaum lub zog magnetic teb yog ib qho tseem ceeb rau kev piav qhia cov magnetic teb.
Cov hlau nplaum muaj zog hu ua cov hlau nplaum ruaj khov, yog li lawv puas tsis demagnetize?
Cov hlau nplaum muaj zog yog lub npe hu ua hlau nplaum ruaj khov, thiab demagnetization tsis cuam tshuam nrog lub sijhawm. Muaj ob yam tseem ceeb uas ua rau demagnetization: kub thiab oxidation. Yog tias qhov kub siab tshaj qhov kub Curie los ntawm 300 degrees Celsius, demagnetization yuav tshwm sim. Yog tias kev tiv thaiv tsis zoo thiab nws yog oxidized, demagnetization kuj tshwm sim. Qhov no kuj yog qhov laj thawj loj tshaj plaws rau qhov tsis ua haujlwm ntawm cov hlau nplaum thaum siv. Cov hlau nplaum muaj zog muaj cov yam ntxwv ntawm qhov me me, lub teeb yuag, thiab muaj zog hlau nplaum, ua rau lawv cov hlau nplaum zoo tshaj plaws rau hnub tim. Cov hlau nplaum, raws li lub cim thib peb tsis tshua muaj hauv ntiaj teb cov khoom siv hlau nplaum ruaj khov, muaj qhov ua tau zoo ntawm tus nqi sib piv thiab tau siv dav hauv kev lag luam xws li lub zog, kev thauj mus los, tshuab, kev kho mob, IT, khoom siv hauv tsev, thiab lwm yam. tshwj xeeb tshaj yog nrog kev txhim kho kev paub kev lag luam sawv cev. los ntawm cov ntaub ntawv thev naus laus zis, lawv tau coj cov kev siv tshiab rau cov khoom siv xws li kev lag luam tsis tshua muaj lub ntiaj teb ruaj khov hlau nplaum, uas ua rau kev lag luam dav dav rau kev lag luam neodymium hlau boron.
