Puas yog txhuas sib nqus?

Thaum koj nug cov lus nug,"Puas yog txhuas sib nqus?"Cov lus teb yooj yim yog tsis muaj. Cov hlau txias txhua hnub yuav tsis lo rau ib daim ntawm txhuas ntawv ci lossis cov txhuas tau. Txawm li cas los xij, cov lus teb tshawb fawb tau ntau dua nuanced thiab nthuav. Thaum txhuas tsis sib nqus nyob rau hauv txoj kev hlau yog, nws muaj kev hloov pauv me me ntawm Magnetism uas yog qhov tseem ceeb rau ntau cov ntawv thov siab.

Ntawm Huawei, peb ntseeg tias muaj kev nkag siab tob ntawm cov khoom siv cov khoom yog qhov tseem ceeb los ua kom muaj kev tshiab. Cov lus qhia no yuav muab cov lus pov thawj tseeb, tus kws tshaj lij-coj cov lus piav qhia ntawm cov teb sib sib zog, txav los ntawm cov lus teb yooj yim rau cov kev kawm yooj yim tom qab nws. Koj yuav kawm tsis tau xwbua li casAluminium tsis yog nyiam cov hlau nplaum uas muaj tab sis kuj pom qhov tshwj xeeb sib nqus phenomena nws ua yeeb yam.

Cov lus teb luv luv vs. kev paub tseeb

Rau txhua qhov siv, lub hom phiaj txhua hnub,Aluminium yog suav tias yog cov hlau tsis sib nqusCov. Qhov no yog vim nws tsis muaj cov cuab yeej ntawmferromagnetism, uas yog cov nyhuv muaj zog haib uas peb pom hauv cov ntaub ntawv zoo li hlau, npib tsib xee, thiab cobalt. Cov no yog cov khoom siv uas cov hlau nplaum muaj kev nyiam.

Txawm li cas los xij, los ntawm kev xav ua Physics, zoo li txhua cov ntaub ntawv cuam tshuam nrog cov hlau nplaum sib xyaw hauv qee txoj kev. Science cais cov kev cuam tshuam no rau ntau hom. Peb feem ntau yog:

1. Ferromagnetism:Lub zog muaj zog heev rau cov sib nqus ntawm cov sib nqus, nrog lub peev xwm los ua cov hlauetized mus tas li. (piv txwv li, hlau)

2. Paramagnetism:Lub zog tsis zoo rau sab nraud sib nqus. (piv txwv li,Tooj dawb, Platinum, titanium)

3. DiamnoNetism:Qhov tsis muaj zog uas tsis muaj zog los ntawm kev sib nqus sab nraud sib nqus. (xws li, tooj liab, carbon, dej)

Yog li ntawd, cov lus teb meej tshaj plaws yog tiasTxhuas yog paramagneticCov. Nws yog qhov tsis muaj zog nyiam ua muaj zog sib nqus, tab sis lub zog no yog li tsaus muag-txhiab txhiab lub sij hawm tsis muaj zog tshaj li ferromagnetism - uas nws yog qhov tsis txaus ntseeg hauv lub neej txhua hnub.

Vim li cas tsis aluminium ferromagnetic? Kev Tshawb Fawb ntawm Electron Spins

Txhawm rau kom nkag siab yog vim li cas Aluminium tsis yog sib nqus, peb yuav tsum tau saib nws cov qauv atomic. Magnetism keeb kwm los ntawm tus cwj pwm ntawm cov tshuab hluav taws xob.

• Hluav Taws Xob Saws:Txhua lub tshuab hluav taws xob ua zoo li cov hlau nplaum me me, nrog ib qho cuab yeej hu ua "kiv." Nyob rau hauv feem ntau atoms, hluav taws xob nyob hauv khub nrog kev sib txawv, uas muaj cov tshuaj tiv thaiv lawv cov nyhuv magnetic.

• Cov tshuab hluav taws xob tsis tau:Ferromagnetism yuav tsum muaj atoms kom muaj ntau cov tshuab hluav taws xob tsis tau.Tooj dawbmuaj tsuas yog ib qho hluav taws xob tsis muaj hluav taws xob hauv nws lub plhaub sab nraud.

• Sib nqus Cov Thawj:Qhov tseem ceeb tshaj plaws, cov ntaub ntawv ferromagetic muaj cov qauv crystal uas tso cai rau lub tshuab hluav taws xob uas nyob hauv atagents nyob rau tib qho kev coj. Cov pawg loj no ntawm cov atoms atoms yog hu uaSib nqus cov tswv cuabCov. Thaum koj nqa cov hlau nplaum nyob ze hlau, cov khoom ntiag tug rau hauv cov kev sib dhos, tsim kom muaj kev nyiam ua tau zoo.

Aluminium tus atomic qauv thiab cov siv lead ua lattice tsis txhawb qhov tsim ntawm cov sib nqus cov sib nqus sib nqus no. Nws ib qho kev siv hluav taws xob ib nrab tuaj yeem cuam tshuam me ntsis los ntawm daim teb sab nraud, tab sis cov atoms tsis txhob xauv rau hauv qhov loj-teev sib nchav. Qhov no yog qhov tseem ceebAluminium tsis yog ferromagnetic.

Lub ntsej muag ze ntawm Aluminium's Paramagnetism

Yog li, txhais li cas nws txhais tau tias txhuas yog paramagnetic?

Thaum koj tso cov teb txhuas hauv cov khoom sib nqus muaj zog, cov tib leeg unpaired electron hauv txhua qhov atom yuav nyiam nws txoj kev tig nrog cov kev taw qhia ntawm daim teb. Qhov no tsim cov me me, ib ntus nim sib nqus.

Cov yam ntxwv tseem ceeb ntawm Paramagnetism suav nrog:

• Lub neej tsis zoo:Lub zog yog tsis muaj zog thiab tsuas yog ntsuas tau nrog cov khoom siv kev kuaj hauv kev kuaj.

• Cov nyhuv ib ntus:Sai li sai tau sab nraud sib nqus teb tau raug tshem tawm, lub tshuab hluav taws xob rov qab mus rau lawv cov kev taw qhia kev ua haujlwm, thiab cov txhuas poob nws cov lus sib tw tam sim ntawd. Nws tsis tuaj yeem sib tw tas mus li.

Kev sib piv ntawm cov khoom siv sib nqus

Txhawm rau muab cov no hauv cov ntsiab lus teb, cov ntaub ntawv no suav cov ntsiab lus tseem ceeb ntawm lub ntsiab ntawm Magnetism.

Eddy tam sim no cov nyhuv: aluminium tus sib xyaw sib nqus

Thaum txhuas tsis yog ferromagnetic, nws muaj lwm yam kev txaus siab nroghloovSib nqus teb. Qhov no yog vim ib qho tshwm sim zoo lieddy kurents.

Raws li Lenz txoj cai lij choj, thaum ib tus neeg xyuas kev coj uatooj dawbTsiv los ntawm kev sib nqus, lossis thaum sib nqus daim teb tsiv los ntawm tus thawj coj, me me, ncig cov hluav taws xob hluav taws xob yog ntxias rau hauv cov hlau. Cov no yog cov "eddy dej."

Cov tshuaj eddy eddy, nyob rau hauv lem, tsim lawv tus kheej sib nqus uastawm tsam qhov kev hloov pauv uas tsim lawvCov. Cov kev coj ua yog qhov qias neeg lossis braking quab yuam.

Koj tuaj yeem pom qhov no hauv kev nqis tes ua:

• Sib nqus braking:Yog tias koj poob lub zog neodymium hlau nplaumnramLub tshuab tuab tuab lossis xaum tooj liab, nws yuav poob qeeb qeeb. Cov hlau nplaum cov lus tsa suab tawm eddy so hauv cov yeeb nkab, uas tsim cov kev sib nqus ntawm daim teb uas nws poob.

• Induction sorting:Hauv kev siv lub zog, lub ntsiab cai no tau siv los cais cov hlau tsis muaj hlau xws li txhuas cov kaus poom los ntawm lwm cov khib nyiab. Cov hlau nplaum muaj zog dhau ntawm cov ntaub ntawv, ntxias eddy so hauv cov txhuas thiab fling nws mus rau hauv ib qho kev sib cais.

Qhov kev sib cuam tshuam no tsis yog raws li kev nyiam tab sis ntawm indectromagnetic induction. Nws yog cov yeeb yam muaj zog uas txawm hais tiasAluminium tsis yog "sib nqus,"Nws txoj kev sib raug zoo nrog Magnetism yog qhov tseem ceeb rau kev siv tshuab.

[Duab: Daim duab uas qhia cov hlau nplaum uas poob los ntawm cov raj Aluminium, nrog cov xub ris, nrog cov xib xub taw qhia eddy dej tsaws thiab ua rau muaj kev cuam tshuam tawm tsam sib nqus. Alt-cov ntawv nyeem: daim duab kos duab eddy tam sim no cov nyhuv tam sim no, qhov twg lub cev ntas stirular

Vim li cas txhuas qhov tsis-ferromagnetic xwm yog ib qho txiaj ntsig tseem ceeb

Qhov tseeb uas txhuas tsis yog ferromagnetic yog ib qho ntawm nws cov kev lag luam tseem ceeb tshaj plaws thiab kev lag luam zoo. Cov cuab yeej no ua rau nws xaiv qhov zoo tshaj plaws rau cov kev siv ntau heev.

• Cov Khoom Siv Hluav Taws Xob thiab Tsev:Txhuas yog dav siv rau rooj plaub smartphone, laptops, thiab cov ntaub thaiv rau cov khoom siv hluav taws xob rhiab. Nws cov xwm tsis-sib nqus uas ua kom nws tsis cuam tshuam nrog cov cuab yeej ntawm cov khoom siv sab hauv, chaw tos txais qhua (GPS), lossis Compass haujlwm ua haujlwm.

• High-voltage thiab Fais Fab Tshuab:Hauv cov busebars thiab high-voltage fais fab kab sib xyaw, txhuas yog cov khoom siv hluav taws xob tsis zoo) uas tshwm sim thaum muaj kev sib nqus ntawm daim teb sib nqus.

• Aerospace thiab Automotive:Ntxiv rau kev ua lub teeb yooj yim, nws cov ntaub ntawv tsis yog-sib nqus yog qhov tseem ceeb rau cov khoom siv ze ntawm cov khoom siv nogigational.

• Khoom Siv Kho Mob:Cheebtsam rau MRI MACHINE thiab lwm cov khoom siv kho mob uas nquag siv cov hlau sib nqus uas feem ntau siv cov kev cuam tshuam txhuas kom tsis txhob muaj kev cuam tshuam sib xyaw thiab ua kom tus neeg mob muaj kev nyab xeeb.
