Kev Ntsuas Cov Yam Ntxim Saib Ntawm Cov Hlau Nplaum Mus Ib Txhis

Kev Ntsuas Hlau Nplaum Mus Ib Txhis: Lub Zeem Muag ntawm Tus Kws Kho Tshuab

Qhov Tseem Ceeb ntawm Kev Ntsuas Kom Tseeb
Yog tias koj ua haujlwm nrog cov khoom sib nqus, koj paub tias kev ua tau zoo pib nrog kev ntsuas raug. Cov ntaub ntawv peb sau los ntawm kev sim hlau nplaum ncaj qha cuam tshuam rau kev txiav txim siab hauv kev tsim kho tsheb, khoom siv hluav taws xob rau cov neeg siv khoom, kev siv tshuab kho mob, thiab kev siv hluav taws xob rov ua dua tshiab.

Plaub Qhov Kev Ntsuas Kev Ua Tau Zoo Tseem Ceeb
Thaum peb ntsuam xyuas cov hlau nplaum tas mus li hauv chav kuaj, peb feem ntau saib plaub qhov tseem ceeb uas txhais lawv lub peev xwm:

Br: Lub Cim Xeeb ntawm Lub Hlau Nplaum
Kev Nyob Twj Ywm (Br):Xav txog qhov no ua lub "nco" ntawm lub hlau nplaum rau kev sib nqus. Tom qab peb tshem tawm lub teb sib nqus sab nraud, Br qhia peb tias cov khoom siv khaws cia lub zog sib nqus ntau npaum li cas. Qhov no muab rau peb lub hauv paus rau lub zog ntawm lub hlau nplaum thaum siv tiag tiag.

Hc: Kev Tiv Thaiv Demagnetization
Kev Ua Haujlwm (Hc):Xav txog qhov no ua lub "lub zog" ntawm lub hlau nplaum - nws lub peev xwm los tiv thaiv kev demagnetization. Peb muab qhov no faib ua Hcb, uas qhia peb tias qhov rov qab xav tau los tshem tawm cov zis hlau nplaum, thiab Hci, uas qhia tias peb xav tau lub zog ntau npaum li cas los tshem tawm qhov sib dhos sab hauv ntawm lub hlau nplaum.

BHmax: Lub Teeb Qhia Txog Lub Hwj Chim
Khoom Siv Zog Siab Tshaj Plaws (BHmax):Qhov no yog tus lej fais fab uas peb rub tawm los ntawm lub voj voog hysteresis. Nws sawv cev rau qhov siab tshaj plaws ntawm lub zog uas cov khoom siv hlau nplaum tuaj yeem xa tawm, ua rau nws yog peb qhov kev ntsuas mus-rau rau kev sib piv ntau hom hlau nplaum thiab qib kev ua tau zoo.

Hci: Kev Ruaj Ntseg Hauv Qab Siab
Kev Sib Tw Hauv Lub Cev (Hci):Rau cov hlau nplaum NdFeB uas muaj kev ua tau zoo niaj hnub no, qhov no yog qhov ua tau los yog ua tsis tau. Thaum cov nqi Hci muaj zog, cov hlau nplaum tuaj yeem tiv taus cov xwm txheej hnyav - suav nrog qhov kub siab thiab cov teb sib nqus tawm tsam - yam tsis muaj kev poob qis ntawm kev ua tau zoo.

Cov Cuab Yeej Ntsuas Tseem Ceeb
Hauv kev xyaum ua, peb vam khom cov khoom siv tshwj xeeb los ntes cov khoom no. Lub hysteresisgraph tseem yog peb lub chaw kuaj mob, kos duab tag nrho BH nkhaus los ntawm kev tswj hwm magnetization voj voog. Hauv pem teb Hoobkas, peb feem ntau hloov mus rau cov kev daws teeb meem portable xws li Hall-effect gaussmeters lossis Helmholtz coils rau kev txheeb xyuas qhov zoo sai.

Kev Ntsuas Cov Hlau Nplaum Uas Muaj Cov Nplaum
Tej yam yuav txawv me ntsis thaum peb simcov hlau nplaum neodymium uas muaj cov nplaumQhov yooj yim ntawm cov nplaum uas ua rau hauv los nrog qee qhov teeb meem kev sim:

Cov Kev Sib Tw Ntaus
Kev Sib Tw Ntaus:Cov txheej nplaum ntawd txhais tau tias lub hlau nplaum yeej tsis nyob zoo hauv cov khoom siv kuaj txheem. Txawm tias qhov sib txawv me me ntawm huab cua tuaj yeem ua rau peb cov kev nyeem ntawv tsis meej, xav tau cov kev daws teeb meem tshiab rau kev teeb tsa kom raug.

Kev Xav Txog Geometry
Kev Xav Txog Daim Ntawv Qhia Txog Yam:Lawv qhov nyias nyias thiab khoov tau xav tau kev teeb tsa tshwj xeeb. Cov qauv teeb tsa uas tsim los rau cov blocks nruj tsis ua haujlwm thaum koj cov qauv kuaj tuaj yeem khoov tau lossis tsis muaj qhov tuab sib npaug.

Cov Kev Cai ntawm Ib puag ncig kev kuaj mob
Cov Kev Cai Rau Kev Rho Tawm Sib Nqus:Ib yam li txhua qhov kev sim hlau nplaum, peb yuav tsum ua tib zoo xav txog kev khaws txhua yam uas tsis yog hlau nplaum ze. Txawm hais tias cov nplaum nws tus kheej tsis muaj hlau nplaum, txhua yam cuab yeej hlau ze lossis lwm yam hlau nplaum yuav ua rau peb cov txiaj ntsig tsis zoo.

Vim Li Cas Kev Ntsuas Thiaj Tseem Ceeb？
Qhov kev pheej hmoo rau kev kuaj xyuas kom raug yog siab heev. Txawm hais tias peb tab tom tsim cov hlau nplaum rau cov tsheb fais fab lossis cov khoom siv kuaj mob, tsis muaj chaw rau qhov yuam kev. Nrog cov hom nplaum uas muaj cov khoom siv rov qab, peb tsis yog tsuas yog kuaj xyuas lub zog ntawm cov hlau nplaum xwb - peb kuj tseem txheeb xyuas qhov ua kom sov tau, vim tias cov txheej nplaum feem ntau ua tsis tiav ua ntej cov hlau nplaum nws tus kheej hauv qhov xwm txheej kub siab.

Lub Hauv Paus ntawm Kev Ntseeg Tau
Thaum kawg ntawm hnub, kev sim ua kom tiav tsis yog tsuas yog kev kuaj xyuas zoo xwb - nws yog lub hauv paus ntawm kev ua tau zoo uas kwv yees tau hauv txhua daim ntawv thov. Cov ntsiab cai tseem zoo ib yam thoob plaws cov hom hlau nplaum, tab sis cov kws tshaj lij ntse paub thaum twg yuav tsum hloov kho lawv cov txheej txheem rau cov xwm txheej tshwj xeeb xws li cov qauv tsim uas muaj nplaum.
