Neodymium Lub tog raj kheej Magnet N52 - Cov qauv pub dawb muaj | Fullzen

N52 hlau nplaum yog hais txog cov hlau nplaum neodymium nrog qib N52, uas yog ib qho ntawm cov qib siab muaj zog sib nqus rau cov hlau nplaum neodymium. Lub "N" qhia tias nws yog cov hlau nplaum neodymium, thiab "52" sawv cev rau lub zog ntawm cov khoom siv hlau nplaum. Cov khoom siv hluav taws xob ntau dua txhais tau tias muaj zog hlau nplaum.

Txawm li cas los xij, cov lus qhia tshwj xeeb rau lub hlau nplaum N52 "muaj zog heev" tuaj yeem sib txawv raws li cov yam xws li qhov loj me, qhov ntev, txheej, thiab chaw tsim khoom.

Cov hlau nplaum neodymium nyob rau hauv cov duab ntawm lub tog raj kheej feem ntau muaj ob tug ncej, sab qaum teb ncej thiab sab qab teb ncej, ib yam li lwm yam hlau nplaum. Cov ncej yog cov ntsiab lus ntawm cov hlau nplaum qhov chaw uas cov hlau nplaum yog qhov muaj zog tshaj plaws thiab cov kab sib nqus ntawm lub zog tawm los yog nkag mus rau cov hlau nplaum.

Rau lub cylindrical neodymium hlau nplaum, sab qaum teb nrhiav tus ncej feem ntau nyob ntawm ib qho ntawm lub tiaj tiaj, thaum sab qab teb nrhiav ncej yog nyob rau ntawm lwm qhov chaw tiaj tus. Cov kab hlau nplaum feem ntau khiav raws qhov ntev ntawm lub tog raj kheej, los ntawm sab qaum teb mus rau sab qab teb ncej.

Cov txheej txheem tshwj xeeb ntawm tus ncej thiab tus cwj pwm ntawm cov hlau nplaum yog ua raws li cov ntsiab lus dav dav ntawm cov hlau nplaum thiab cov khoom ntawm cov hlau nplaum ruaj khov. Nws tseem ceeb heev uas yuav tsum nco ntsoov tias cov ncej ntawm cov hlau nplaum tsis tuaj yeem raug cais tawm ntawm ib leeg; rhuav cov hlau nplaum rau hauv cov khoom me me yuav tsuas tsim cov hlau nplaum me me, txhua tus nrog lawv tus kheej sab qaum teb thiab sab qab teb ncej.

Cov hlau nplaum tsim los ntawm cov hlau nplaum ruaj khov cylindrical yog qhov nyuaj dua li cov qauv lej yooj yim vim cov duab thiab cov khoom ntawm cov hlau nplaum. Txawm li cas los xij, ib qho piv txwv ntawm cov hlau nplaum sib nqus raws li axis ntawm cov hlau nplaum ntev cylindrical tuaj yeem muab tau los ntawm Biot-Savart txoj cai, piv txwv li cov hlau nplaum yog magnetized raws nws qhov ntev thiab cov neeg soj ntsuam nyob deb ntawm cov hlau nplaum qhov kawg:
= 0⋅ 2 ⋅ 2B = 2π⋅rµ⋅M
Qhov twg:
B yog lub zog ntawm lub zog sib nqus ntawm qhov deb r ntawm lub axis ntawm lub hlau nplaum.
0μ0​ yog qhov permeability ntawm qhov chaw dawb (4 × 10−7 T⋅m/A4π×10−7T⋅m/A).
M yog qhov magnetization ntawm cov khoom siv hlau nplaum, uas sawv cev rau lub zog magnetic ib chav tsev ntim (A/mA/m).
Cov mis no muab kev kwv yees ntawm lub zog ntawm lub zog sib nqus raws txoj kab ntawm lub hlau nplaum cylindrical ntev. Nco ntsoov tias qhov kev faib tawm ntawm lub zog sib nqus tiag tiag tuaj yeem cuam tshuam los ntawm qhov ntev, txoj kab uas hla, kev coj ua magnetization, thiab cov khoom siv tshwj xeeb. Yog xav tau kev suav kom raug dua, tshwj xeeb tshaj yog rau cov hlau nplaum uas tsis sib xws magnetization lossis cov duab sib txawv, kev ua lej lossis software tshwj xeeb yuav tsum tau ua.
