Raws li cov khoom siv, cov hlau nplaum ruaj khov tsim nrog cov khoom siv ferromagnetic nyuaj, uas yog cov uas, tom qab tau magnetized, tswj lawv cov khoom sib nqus kom txog thaum lawv demagentized, uas yog qhov tshwm sim uas tshwm sim thaum siv cov hlau nplaum sib txawv ntawm qhov pib. .
Cov khoom siv rau kev tsim cov hlau nplaum ruaj khov yog:
Cov hlau nplaum ntawm neodymium, hlau thiab boron yog siv rau kev tsim khoom ntawm NdFeB, NIB thiab Neo.
Nws yog cov alloy ntawm aluminium, npib tsib xee thiab cobalt thiab qee zaum tooj liab, hlau thiab titanium siv.
Cobalt-Samarium. Raws li nws lub npe qhia, nws yog tsim los ntawm cov hlau ntawm samarium thiab cobalt.
Nws yog cov hlau crystallized hauv cubic system.
Txhua lub hlau nplaum ruaj khov tsim ib qho chaw sib nqus, zoo ib yam li lwm cov hlau nplaum, uas nyob ib puag ncig ntawm cov hlau nplaum hauv cov qauv sib txawv. Qhov loj ntawm cov hlau nplaum muaj feem xyuam nrog qhov loj ntawm cov hlau nplaum thiab nws lub zog. Txoj hauv kev yooj yim tshaj plaws kom pom cov hlau nplaum uas tsim los ntawm cov hlau nplaum tas mus li yog kom tawg cov hlau nplaum nyob ib ncig ntawm cov hlau nplaum, uas tau taw qhia sai raws cov kab teb.
Txhua tus hlau nplaum ruaj khov muaj ob tus ncej, hu ua sab qaum teb thiab sab qab teb, txawm hais tias lawv tuaj yeem hu ua A thiab B. Cov ncej zoo sib xws tau sib tw thaum cov ncej sib txawv nyiam. Nws yuav siv sij hawm ntau ntawm kev siv zog los ua kom cov ncej ntawm cov hlau nplaum ua ke, thaum yuav tsum tau siv zog tshem tawm cov ncej ntawm kev nyiam. Cov hlau nplaum uas muaj zog tshaj plaws nyiam nrog cov quab yuam uas lawv tuaj yeem ua rau raug mob los ntawm pinching ntawm daim tawv nqaij ntawm lawv.
Tau ntau txhiab xyoo, cov hlau nplaum ruaj khov yog tib neeg hlau nplaum uas tib neeg muaj. Lub electromagnet tsuas yog tsim nyob rau hauv 1823. Ua ntej ntawd, hlau nplaum feem ntau yog novelties. Siv cov khoom siv hluav taws xob, nws muaj peev xwm ua kom muaj qhov tam sim no hauv txhua yam khoom siv ferromagnetic, xws li hlau clip. Txawm li cas los xij, cov nyhuv ploj mus sai sai.
4 Hom Cov Hlau nplaum tas mus li

Thaum xaiv cov hlau nplaum zoo rau cov khoom lag luam lossis cov hlau nplaum-raws li qhov system, manufacturers yuav tsum xav txog cov hauv qab no.
- Simplified tsim cov cai
- Lub kaw lus yuav tsum muaj qhov sib nqus tsis tu ncua tab sis muaj kev txwv tsis pub nkag mus rau lub zog txuas ntxiv ntawm kev muaj ib qho tsis muaj txiaj ntsig
- txwv lossis txwv qhov chaw yuav tsum tau muaj
- Tus nqi qis dua
- Txwv tsis pub nkag los yog txwv

Cov hlau nplaum ruaj khov
Cov hlau nplaum yog tsim los ntawm cov khoom hu ua hlau nplaum. Thaum cov khoom ntawm cov hlau nplaum tsis ploj mus thoob plaws lub sijhawm nws paub tias yog cov hlau nplaum ruaj khov.
Magnetism yog qhia los ntawm cov khoom ferromagnetic ib yam nkaus. Qee cov ntaub ntawv yog ob peb alloys ntawm hlau thiab npib tsib xee. Txoj kev ntawm cov domains yog oriented nyob rau hauv ib tug ferromagnetic tshuaj nyob ntawm seb cov khoom ntawm magnetism.
Cov teb sib nqus uas tau tsim ib tus zuj zus tshem tawm lawv tus kheej tawm thaum cov domains randomly oriented. Ib qho chaw sib nqus sib nqus tuaj yeem tsim los ntawm kev txo qhov randomization ntawm tus sau los ntawm kev cuam tshuam nws los ntawm hluav taws xob teb. Qhov no yog ib qho ntawm cov txheej txheem los ntawm cov khoom siv electromagnets. Tab sis yog tias cov thawj tswj hwm twb tau teem tseg xws li lawv taw tes rau tib qho kev taw qhia, txawm tias tsis muaj kev cuam tshuam sab nraud lawv yuav tsim ib qho chaw sib nqus sib nqus. Cov no yog cov hlau nplaum ruaj khov.
Sib nqus cwj pwm
Thaum muab cov hlau nplaum nplaum rau ntawm cov tshuaj ferromagnetic cov thawj tau npaj los tsim cov hlau nplaum thiab tsis rov qab mus rau lawv lub xeev li qub. Thaum tsav tsheb yog xoom thiab txawm tias cov thawj coj tsis tau rov kho lawv tus kheej kom zoo li lub sijhawm cov khoom siv los demagnetize lossis tseem magnetised rau yog hu ua remanence. Yog tias peb sim muab cov cuab yeej sib nqus rov qab mus rau xoom los ntawm kev siv lub teb nyob rau hauv ib qho kev taw qhia tus nqi ntawm qhov rov qab teb uas yuav tsum tau demagnetise cov khoom no hu ua coercivity. Qhov tsis tuaj yeem khaws cov khoom sib nqus ntawm cov khoom yog hu ua hysteresis.
Koj puas tau pom tias cov ntsia hlau hlau uas tau txuas nrog cov hlau nplaum rau qee lub sijhawm nyiam lwm cov hlau tsis sib nqus hlau rau lub sijhawm luv txawm tias tom qab nws tau raug tshem tawm ntawm cov hlau nplaum? Qhov no yog vim hais tias cov thawj ntawm cov ntsia hlau hlau tau reoriented. Cov nyhuv no tsis muaj zog thiab poob sai sai. Yog li ntawd, tus ntsia thawv hlau yuav tsis raug suav hais tias yog cov hlau nplaum ruaj khov.
Qhov txiaj ntsig tseem ceeb ntawm cov hlau nplaum ruaj khov dua li lwm hom yog tias nws tsis tas yuav muaj cov khoom siv hluav taws xob txuas ntxiv (hauv cov khoom siv hluav taws xob, hluav taws xob) kom pom cov hlau nplaum. Piv txwv li, cov hlau nplaum tas mus li yog siv los ua cov koob koob.
Yuav ua li cas yog ib tug ruaj khov hlau nplaum tsim
Cov hlau nplaum tas mus li yog tsim los ntawm cov qauv sab hauv ntawm ib yam khoom. Nyob rau hauv lub atoms yog cov electrons thiab nuclei ntawm lub atoms, uas lawv tus kheej yog inherently magnetic thiab spin zoo li tej daim ntawm hluav taws xob. Tsis tas li ntawd, los ntawm kev tig lub electron nyob ib ncig ntawm lub nucleus ntawm lub electron circuits, ib tug magnetic teb yog tsim.
Yog li ntawd, qhov sib nqus ntawm cov hlau nplaum ruaj khov yog qhov tshwm sim ntawm peb yam hauv lub microscopic saib: electron spin, nucleus spin, thiab electron orbits.
Ntau cov ntaub ntawv tsis muaj cov khoom sib nqus mus tas li, vim tias cov khoom sib nqus ntawm txhua qhov ntawm cov khoom no randomly taw tes rau txhua qhov kev qhia thiab ua rau ib leeg. Tab sis nyob rau hauv cov ntaub ntawv ferromagnetic, cov teb uas tshwm sim los ntawm kev sib hloov ntawm cov nucleus thiab cov hluav taws xob thiab cov hluav taws xob hluav taws xob tau ntxiv ua ke, ua kom sib luag thiab tsim kom muaj ib qho chaw sib nqus mus tas li.
