Yuav ua li cas nce magnetic dispersion zoo ntawm muaj zog magnetic NdFeB
Qhov sib nqus resonance teebmeem ntawm ntau hom sib zog nqus sib nqus NdFeB yog txawv. Tom qab ntawd, lub zog NdFeB muaj zog li cas ntxiv rau qhov sib txawv ntawm kev sib nqus? Cia peb qhia koj kom meej:
Qhov sib zog nuv ntses NdFeB ua kom lub cev nqus tau zoo npaum li cas?
Ib qho ntawm cov dej num ntawm cov khoom sib nqus hlau sib nqus ntawm cov muaj zog magnetic NdFeB yog ua rau lub zog ntawm sib nqus ntawm huab cua magnetic ntau npaum li sai tau, thiab nws yog qhov yooj yim kom nce qhov ceev nrawm ntawm Circuit Court, seem thaj tsam ntawm cov hlau yog hloov. Qhov me me ntawm qhov seem hauv kab, qhov siab zog tam sim no.
Lub hauv paus ntsiab lus ntawm kev ua kom muaj huab cua ua haujlwm nrov yog qhov sib deev tib leeg sib txawv thiab sib ntxig sib deev. Lub ntsiab ntawm cov cuab yeej muaj zog magnetic NdFeB yog:
(1) Hloov seem hauv kab hauv qhov sib txuam sib nqus
(2) Txhob siv cov hlau nplaum sib txuas ntawm kev sib ntaus sib tua
Cov hlau nplaum uas muaj zog magnetic NdFeB feem ntau yog cylindrical, toroidal, thiab muaj kev sib raug zoo ntawm lawv txoj kab uas hla, cov pa thiab cov khoom sib nqus. Lub magnetization ntawm ib cov hlau nplaum tas li yog qhov ntim, uas tau hais ua ntej, thiab qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov chaw. Nws yog thaj chaw ntau npaum li cas, thiab Φ yog qhov sib txawv ntawm qhov sib txawv. Chav tsev yog qhov zoo ntawm qhov kev sib tshuam ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib nqus. .
Nrog cov quab yuam ntawm cov quab yuam zog ntawm cov khoom muaj zog magnetic NdFeB, cov khoom siv rov ua dua rov qab, uas yog nyob ze rau ntawm cov huab cua permeability I. Yog li, qhov sib txawv ntawm cov hlau nplaum ntawm nws tus kheej tsis negligible, thiab yog li qhov ntev ntawm cov hlau nplaum tsis tu ncua nyob rau hauv cov txuj ci magnetization tsis ntev heev.
Qhov sib nqus qhov sib nqus tsis yog yooj yim heev, tsuas yog thaum tsis tshua muaj tshwm sim, cov kab hauv hlau nplaum tsis muaj cov khoom uas tsis tuaj yeem nkag mus. Muaj cov hlau nplaum xwb thiab tsis muaj cov hlau nplaum tsis-txheej txheem. Txawm li cas los xij, los ntawm kev hloov qhov ntsuas ntawm qhov sib luag ntawm cov sib nqus, qhov tsim nyog ntawm cov hlau nplaum thiab cov hlau nplaum yuav tuaj yeem ua rau lub zog ntom ntom ntom ntawm qhov sib txawv ntawm kev ua haujlwm.
