Ferrite hlau nplaum muaj qhov zoo endogenous coercivity kub coefficient (ntxiv rau 0.27 feem pua / degree Celsius txheeb ze rau ib puag ncig), thiab tsuas yog ferrite qhia cov cuab yeej no ntau heev. Txawm li cas los xij, cov khoom sib nqus tau txo qis nrog qhov kub thiab txias (nws muaj qhov tsis zoo ntawm qhov kub thiab txias coefficient ntawm -0.2 feem pua / degree Celsius. Qhov kawg tshwm sim yog tias cov hlau nplaum ferrite tuaj yeem siv rau qhov kub thiab txias tsis muaj teeb meem me me.
Cov hlau nplaum Ferrite tuaj yeem siv tau ntawm qhov kub txog li 250 degrees Celsius (qee zaus nce mus txog 300 degrees Celsius), ua rau lawv tsim nyog rau cov motors thiab feem ntau cov ntawv siv kub. Thaum kub qis dua xoom, xws li -10 txog -20 degrees Celsius, cov hlau nplaum ferrite yuav pib ua kom muaj zog tensile txo. Uas yog hais tias, qhov kub thiab degree ntawm attenuation nyob ntawm seb cov duab ntawm cov hlau nplaum thiab tshwj xeeb rau daim ntawv thov. Hauv kev siv feem ntau Cov yam ntxwv kub ntawm cov hlau nplaum xa mus rau qhov sib txawv thiab cov yam ntxwv ntawm cov khoom sib nqus hloov nrog qhov kub thiab txias. Feem ntau hais lus, cov hlau nplaum ferrite muaj cov khoom sib nqus ntau dua ntawm qhov kub thiab txias, thiab lawv cov khoom sib nqus maj mam txo qis thaum qhov kub nce. Thaum qhov kub nce mus txog ib qho nqi, cov khoom sib nqus yuav txo qis thiab nkag mus rau thaj tsam kub ntxhov. Cov khoom sib nqus qhia cov lus teb rhiab heev nyob ze qhov ntsuas kub tseem ceeb, uas yog hu ua "Critical exponent".
Qhov kub coefficient yog hais txog tus lej tus nqi ntawm cov khoom sib nqus ntawm cov hlau nplaum ua haujlwm ntawm qhov kub thiab txias. Qhov kub coefficient feem ntau yog qhia raws li qhov feem pua ntawm kev sib nqus sib nqus thaum qhov kub hloov pauv los ntawm 1 degree . Qhov loj ntawm qhov kub coefficient yog nyob ntawm hom thiab zoo ntawm cov khoom sib nqus. Rau cov hlau nplaum ferrite, lawv qhov kub coefficient feem ntau yog me me, xws li ntawm 0.01 feem pua rau 0.05 feem pua , uas tso cai rau lawv cov khoom sib nqus kom muaj kev ruaj khov nyob rau ntau qhov kub thiab txias.
Hauv kev siv tswv yim, qhov cuam tshuam ntawm qhov kub ntawm cov hlau nplaum ferrite yuav tsum tau txiav txim siab tag nrho. Piv txwv li, nyob rau hauv lub teb ntawm lub hwj chim kis tau tus mob thiab transformation, ferrite hlau nplaum yog feem ntau siv raws li lub hauv paus ntawm transformers. Nyob rau hauv ib puag ncig kub, cov khoom sib nqus ntawm cov hlau nplaum ferrite tuaj yeem cuam tshuam tsis zoo, ua rau kev puas tsuaj rau transformer. Yog li ntawd, qhov ntsuas kub yuav tsum raug coj mus rau hauv tus account hauv kev tsim thiab tsim cov txheej txheem, thiab cov kev ntsuas sib raug yuav tsum tau coj los xyuas kom meej tias cov hlau nplaum ferrite tuaj yeem ua haujlwm ib txwm nyob ntawm ntau qhov kub.
Zuag qhia tag nrho, cov yam ntxwv ntawm qhov kub thiab txias coefficient ntawm ferrite hlau nplaum yog qhov tseem ceeb heev hauv cov khoom sib nqus. Lawv cov kev tshawb fawb thiab kev txawj ntse yog qhov tseem ceeb heev rau kev ua kom zoo sib nqus kev ua tau zoo thiab txhim kho daim ntawv thov ntawm cov khoom sib nqus ntawm qhov kub thiab txias, kev khiav hauj lwm kub tsis txaus los tsim cov nyhuv no.
