Cov hlau nplaum tuaj yeem ruaj khov los tiv thaiv qhov kev hloov pauv ntawm kev ua tau zoo los ntawm kev poob tsis tau.
Intrinsic Coercive Force, Hci- Oersted ntsuas ntawm cov khoom muaj peev xwm los tiv thaiv tus kheej-demagnetization.
Isotropic (tsis-oriented)- Cov khoom siv tsis muaj kev xav tau ntawm kev sib nqus orientation, uas tso cai rau kev sib nqus hauv txhua qhov kev taw qhia.
Magnetizing Force- Lub zog magnetomotive ib chav tsev ntev ntawm txhua qhov chaw hauv ib lub voj voog sib nqus. Chav tsev ntawm lub zog magnetizing yog Oersted hauv GCS system.
Cov khoom siv hluav taws xob siab tshaj plaws(BH) max - Muaj ib qho taw qhia ntawm Hysteresis Loop ntawm qhov khoom ntawm magnetizing force H thiab induction B mus txog qhov siab tshaj plaws. Tus nqi siab tshaj yog hu ua Maximum Energy Product. Lub sijhawm no, qhov ntim ntawm cov khoom siv hlau nplaum yuav tsum tau ua kom lub zog muab rau hauv nws ib puag ncig yog qhov tsawg kawg nkaus. Qhov kev ntsuas no feem ntau yog siv los piav qhia tias "muaj zog" cov khoom siv hlau nplaum ruaj khov li cas. Nws lub tsev yog Gauss Oersted. Ib MGOe txhais tau tias 1,000,000 Gauss Oersted.
Sib nqus induction- B -Flux ib cheeb tsam ntawm ib seem ib txwm mus rau kev taw qhia ntawm txoj kev sib nqus. Ntsuas hauv gauss.
Ua haujlwm kub siab tshaj plaws- Qhov kub siab tshaj plaws ntawm kev raug cov hlau nplaum tuaj yeem ua rau tsis muaj qhov tsis txaus ntseeg ntev lossis kev hloov pauv ntawm cov qauv.
North Ncej- Tus ncej hlau nplaum uas nyiam thaj chaw North Ncej.
Oersted, Aw- Ib chav ntawm magnetizing quab yuam hauv GCS system. 1 Oersted sib npaug 79.58 A / m hauv SI system.
Permeability, Recoil- Qhov nruab nrab txoj kab nqes ntawm lub voj me hysteresis.
Polymer Bonding -Magnet hmoov yog tov nrog ib tug polymer carrier matrix, xws li epoxy. Cov hlau nplaum yog tsim nyob rau hauv ib tug tej yam zoo li, thaum lub carrier yog solidified.
Residual Induction,Br -Flux density - Ntsuas hauv gauss, ntawm cov khoom sib nqus tom qab tau tag nrho cov hlau nplaum nyob rau hauv lub kaw lus kaw.
Rare Earths Magnets -Cov hlau nplaum ua los ntawm cov ntsiab lus nrog tus lej atomic ntawm 57 txog 71 ntxiv rau 21 thiab 39. Lawv yog lanthanum, cerium, praseodymium, neodymium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, thiab scandalous. yttrium.
Remanance, Bd-Magnetic induction uas tseem nyob rau hauv ib tug sib nqus Circuit Court tom qab tshem tawm ntawm ib tug thov magnetizing quab yuam. Yog tias muaj qhov sib txawv ntawm huab cua hauv Circuit Court, qhov remenance yuav tsawg dua qhov seem induction, Br.
Reversible Temperature Coefficient- Ib qho kev ntsuas ntawm qhov hloov pauv hloov pauv hauv cov dej ntws los ntawm qhov kub thiab txias.
Residual Induction -Br Tus nqi ntawm induction ntawm qhov taw tes ntawm Hysteresis Loop, uas Hysteresis voj hla B axis ntawm xoom magnetizing quab yuam. Lub Br sawv cev rau qhov siab tshaj plaws sib nqus flux ceev tso zis ntawm cov khoom no yam tsis muaj sab nraud magnetic teb.
Saturation- Ib tug mob nyob rau hauv uas induction ntawmferromagneticcov khoom tau mus txog nws tus nqi siab tshaj plaws nrog kev nce ntawm kev siv lub zog magnetizing. Txhua lub caij sib nqus hauv theem pib tau dhau los ua kev taw qhia nyob rau hauv ib qho kev taw qhia ntawm cov xwm txheej saturation.
Sintering- Kev sib txuas ntawm cov hmoov sib txuas los ntawm kev siv cov cua sov kom muaj ib lossis ntau dua ntawm ob peb lub tswv yim ntawm atom txav mus rau hauv cov particle contact interfaces tshwm sim; Cov txheej txheem yog: viscous flow, kua theem daws-ua nag lossis daus, nto diffusion, bulk diffusion, thiab evaporation-condensation. Densification yog ib txwm tshwm sim ntawm sintering.
Nto Coatings- Tsis zoo li Samarium Cobalt, Alnico thiab ceramic cov ntaub ntawv, uas yog corrosion resistant,Neodymium hlau boronCov hlau nplaum yog raug rau corrosion. Raws li daim ntawv thov hlau nplaum, cov txheej txheem hauv qab no tuaj yeem xaiv los siv rau ntawm qhov chaw ntawm Neodymium Iron Boron hlau nplaum - Zinc lossis Nickel.
