Thaum koj piv cov hlau nplaum, tus lej qib siab dua tsis tau txhais tau tias muaj zog tuav ntau dua. Daim ntawv qhia lub zog hlau nplaum yuav pab koj nkag siab li cas neodymium, ferrite, samarium cobalt, thiab alnico hlau nplaum sib txawv hauv qib, teb lub zog, kub tsis kam, thiab kev siv raug. Koj kuj yuav tsum tau saib tshaj cov ntawv sau xws li N35 lossis N52. Cov hlau nplaum loj, cov duab, qhov sib txawv ntawm huab cua, lub hom phiaj steel, txheej, thiab kev ua haujlwm kub tuaj yeem hloov tau tiag tiag -kev ua haujlwm hauv ntiaj teb. Hauv phau ntawv qhia no, koj yuav kawm paub nyeem cov qib hlau nplaum, sib piv kev ntsuas lub zog, thiab xaiv cov hlau nplaum zoo rau koj daim ntawv thov.
Magnet Strength txhais li cas?
Lub zog hlau nplaum yog tsim los ntawm ob peb qhov sib txawv, thiab kev nkag siab txhua tus yuav pab koj xaiv cov hlau nplaum zoo.
Residual Induction (Br)
Residual induction, los yog Br, yog ntau npaum li cas magnetism nyob twj ywm hauv ib lub hlau nplaum thaum nws tag nrho magnetized. Xav txog nws raws li cov hlau nplaum lub zog raw, ntsuas hauv Gauss lossis Tesla. Br siab dua feem ntau txhais tau tias muaj zog hlau nplaum, tab sis nws tsis yog daim duab tag nrho. Ob lub hlau nplaum nrog tib Br tuaj yeem rub sib txawv nyob ntawm lawv qhov loj thiab cov duab.
Pull Force lossis Holding Force
Rub lub zog, lossis tuav lub zog, yog tus lej uas koj nyiam tshaj plaws: qhov hnyav npaum li cas cov hlau nplaum tuaj yeem nqa lossis tuav tawm ntawm qhov chaw steel. Tsis zoo li Br, rub quab yuam tsis yog cov khoom siv ruaj khov. Nws nyob ntawm cov hlau nplaum qhov loj thiab cov duab, qhov tuab ntawm cov hlau nws kov, thiab qhov sib txawv ntawm lawv. Tias yog vim li cas ob lub hlau nplaum uas muaj qib tib yam tuaj yeem muaj qhov sib txawv ntawm kev rub tawm thaum lawv raug txiav rau hauv cov duab sib txawv.

FAQ
Q: Dab tsi yog hom hlau nplaum ruaj khov?
A: Neodymium (NdFeB) yog cov khoom siv hlau nplaum ruaj khov uas muaj zog tshaj plaws niaj hnub no. Samarium cobalt los tom ntej, tshwj xeeb tshaj yog nyob rau hauv siab - kub kub, ua raws li alnico thiab ferrite.
Q: Puas yog N52 muaj zog dua N35?
A: Yog. Ntawm qhov loj me, N52 yog kwv yees li 30-40% muaj zog dua N35. Tus lej tom qab N qhia txog cov khoom siv hluav taws xob siab tshaj plaws, yog li tus lej siab dua txhais tau tias cov hlau nplaum muaj zog dua.
Q: Puas yog qib hlau nplaum siab dua ib txwm txhais tau tias muaj zog rub ntau dua?
A: Tsis tas li. Qib qhia koj lub zog ntawm qhov loj me, tab sis rub lub zog kuj nyob ntawm cov duab, tuab, thiab cov hlau nplaum tuav dab tsi. Ib qho me me siab - qib hlau nplaum tseem tuaj yeem rub tsawg dua qhov qis dua - qib ib.
Q: Cov hlau nplaum twg yog qhov zoo tshaj plaws rau kev siv siab - kub?
A: Alnico thiab samarium cobalt tuav cov cua sov zoo tshaj plaws, nrog alnico tiv taus qhov kub siab tshaj plaws ntawm txhua hom. Tus qauv neodymium tsis muaj zog thaum nws ua kom sov, txawm tias siab - cov qib kub zoo li N42SH tuav tau zoo dua.
Q: Puas yog cov hlau nplaum ferrite pheej yig dua li cov hlau nplaum neodymium?
A: Yog lawm, ferrite (ceramic) hlau nplaum raug nqi tsawg dua neodymium, uas yog vim li cas lawv muaj nyob rau hauv loj - ntim los yog pob nyiaj siv - rhiab heev. Kev lag luam tawm - tawm yog tias ferrite tsis muaj zog rau nws qhov loj me.
Q: Magnet rub quab yuam ntsuas li cas?
A: Rub quab yuam yog ntsuas los ntawm kev ntsuas ntau npaum li cas ncaj nraim -kab quab yuam nws yuav siv los rub lub hlau nplaum tawm ntawm lub tiaj tiaj steel phaj ntawm lub teeb tuab. Nws feem ntau yog muab hauv phaus lossis kilograms, thiab cov txiaj ntsig tuaj yeem hloov pauv nyob ntawm qhov ntsuas qhov tseeb.
