(Demagnetization Curves rau N40UH Neodymium Magnet)
Cov hlau nplaum tau fascinated tib neeg rau ntau pua xyoo, qhia txog lub hwj chim txaus nyiam uas zoo li piav tsis tau.Hauv plawv ntawm lub zog hlau nplaum yog qhov demagnetization nkhaus, lub ntsiab lus tseem ceeb hauv kev nkag siab nws cov khoom sib nqus.Hauv tsab ntawv blog no, peb pib taug kev mus rau demystify lub demagnetization nkhaus, nthuav tawm cov lus zais tom qab nws kev tsim kho thiab nws qhov tseem ceeb hauv ntau daim ntawv thov.Yog li, cia peb dhia mus rau hauv lub ntiaj teb ntawm cov hlau nplaum thiab tshawb nrhiav qhov tshwm sim nthuav!
Demagnetization nkhaus tshaj tawm
Ib qho demagnetization nkhaus, tseem hu ua magnetization nkhaus lossis hysteresis voj, qhia txog tus cwj pwm ntawm cov khoom siv hlau nplaum thaum raug hloov pauv magnetic teb.Nws qhia tau hais tias kev sib raug zoo ntawm lub zog ntawm lub magnetic teb thiab qhov tshwm sim magnetic induction los yog flux ceev.Los ntawm plotting magnetic teb zog (H) ntawm x-axis thiab magnetic flux ceev (B) ntawm y-axis, demagnetization curves cia peb to taub thiab txheeb xyuas cov khoom sib nqus ntawm cov khoom.
Nkag siab tus cwj pwm ntawm cov khoom sib nqus
Los ntawm saib cov demagnetization curves, peb tuaj yeem txheeb xyuas qhov tseem ceeb ntawm cov khoom siv tus cwj pwm hauv ntau qhov sib nqus.Cia peb tshawb txog peb yam tseem ceeb:
1. Saturation point: Thaum xub thawj, qhov nkhaus slopes nce sharply kom txog rau thaum nws mus txog rau ib tug pib, thaum lub sij hawm uas tsis muaj kev nce nyob rau hauv magnetic teb zog yuav cuam tshuam qhov flux ceev.Qhov no taw tes qhia qhov saturation ntawm cov khoom.Cov ntaub ntawv sib txawv muaj cov ntsiab lus sib txawv, uas sawv cev rau lawv lub peev xwm kom nyob twj ywm hauv cov hlau nplaum muaj zog.
2. Coercivity: txuas ntxiv raws qhov nkhaus, lub zog sib nqus lub zog txo, ua rau txo qis hauv cov hlau nplaum sib nqus.Txawm li cas los xij, thaum cov khoom khaws cia ib co degree ntawm magnetization, yuav muaj ib tug point qhov twg qhov nkhaus intersects x-axis.Qhov kev sib tshuam no sawv cev rau lub zog quab yuam, lossis kev quab yuam, uas qhia txog cov khoom siv tiv thaiv demagnetization.Cov khoom siv nrog kev sib zog siab yog siv cov hlau nplaum ruaj khov lossis lwm yam kev siv hlau nplaum ruaj khov.
3. Remanence: Thaum lub zog magnetic teb mus txog xoom, qhov nkhaus sib tshuam y-axis kom muab cov remanence flux ceev los yog remanence.Qhov kev ntsuas no qhia txog qib uas cov khoom tseem sib nqus txawm tias tom qab tshem tawm sab nraud magnetic teb.High remanence yog qhov tseem ceeb rau cov ntawv thov uas xav tau kev coj tus cwj pwm sib nqus mus ntev.
Daim ntawv thov thiab qhov tseem ceeb
Demagnetization curves muab kev pom zoo rau kev xaiv cov khoom siv thiab kev ua kom zoo rau ntau yam kev siv.Nov yog qee qhov piv txwv tseem ceeb:
1. Motors: Paub txog qhov demagnetization nkhaus pab tsim lub cev muaj zog nrog cov khoom zoo sib nqus uas tuaj yeem tiv taus siab sib nqus teb yam tsis muaj demagnetization.
2. Sib nqus cov ntaub ntawv khaws cia: Demagnetization curves pab engineers txhim kho cov ntaub ntawv sib nqus zoo nrog kev sib koom tes txaus rau kev ruaj ntseg thiab ruaj khov cov ntaub ntawv.
3. Electromagnetic Devices: Tsim inductor cores thiab transformers yuav tsum tau ua tib zoo xav txog demagnetization curves kom haum rau cov khoom siv hluav taws xob thiab khoom siv.

Muab tso rau hauv lub ntiaj teb ntawm cov hlau nplaum los ntawm lub lens ntawm demagnetization curves, qhia qhov nyuaj ntawm cov khoom siv hlau nplaum thiab lawv cov kev siv.Los ntawm kev siv lub zog ntawm qhov nkhaus no, engineers tab tom ua txoj hauv kev rau kev txhim kho tshiab thoob plaws ntau thaj chaw, ua kom pom kev thev naus laus zis yav tom ntej.Yog li tom ntej no koj tuaj hla cov hlau nplaum, siv sijhawm ib pliag kom nkag siab txog kev tshawb fawb tom qab nws cov hlau nplaum thiab cov lus zais zais hauv qhov yooj yim demagnetization nkhaus.
