Aluminium tsis yog hlau nplaum

Aluminium, chemical symbol Al, tus lej atomic 13, yog ib lub teeb silver-dawb hlau. Nws yog cov hlau ntau tshaj plaws nyob rau hauv lub ntiaj teb crust. Nyob rau hauv cov nqe lus ntawm magnetism, aluminium yog cais raws li cov khoom tsis sib nqus lossis paramagnetic. Qhov no txhais tau hais tias nws tsis pom muaj zog hlau nplaum zoo li cov ntaub ntawv ferromagnetic.

Lub hauv paus ntawm Magnetism

Thaum peb tham txog hlau nplaum, peb feem ntau xav txog tej yam xws li hlau, cobalt, thiab npib tsib xee vim lawv muaj zog attraction rau hlau nplaum. Qhov tseeb, muaj peb hom kev sib nqus ntawm cov khoom siv tseem ceeb:

1. Ferromagnetic: Cov ntaub ntawv xws li hlau, cobalt thiab npib tsib xee muaj zog rau cov hlau nplaum thiab tuaj yeem ua cov hlau nplaum lawv tus kheej.
2. Paramagnetic: Cov ntaub ntawv no muaj qhov tsis muaj zog txaus rau cov hlau nplaum thiab tsis khaws lawv cov hlau nplaum thaum cov hlau nplaum sab nraud raug tshem tawm..
3. Diamagnetism: Cov ntaub ntawv xws li tooj liab thiab bismuth ua tau ib qho chaw sib nqus sib nqus nyob rau hauv lub xub ntiag ntawm lwm qhov chaw sib nqus, tab sis lub zog tsis muaj zog heev.

Magnetism ntawm Aluminium

Nyob rau hauv cov nqe lus ntawm magnetism, aluminium yog cais raws li cov khoom tsis sib nqus lossis paramagnetic. Qhov no txhais tau hais tias nws tsis pom muaj zog hlau nplaum zoo li cov ntaub ntawv ferromagnetic.

Aluminium's paramagnetism tshwm sim los ntawm kev npaj ntawm nws cov electrons. Aluminium muaj ib qho hluav taws xob tsis sib xws hauv nws lub plhaub sab nrauv, thiab raws li quantum physics, unpaired electrons pab rau paramagnetism. Txawm li cas los, vim qhov teebmeem no qaug zog heev, aluminium's magnetism feem ntau nyuaj los kuaj pom hauv lub neej txhua hnub.

Daim ntawv thov thiab qhov tseem ceeb

Nkag siab txog cov khoom tsis sib nqus ntawm aluminium yog qhov tseem ceeb rau ntau yam kev siv:

• Hluav taws xob conductor: Aluminium tsis muaj zog cuam tshuam nrog cov hlau nplaum ua rau nws yog ib qho khoom siv zoo tshaj plaws rau cov kab xa hluav taws xob vim nws tsis cuam tshuam nrog kev khiav ntawm hluav taws xob..
• Cookware: Aluminium cookware yog nrov vim nws tsis hnov ​​​​mob nrog hlau nplaum lossis sib nqus induction, Nws yog ib qho tseem ceeb rau induction cooktops.
• Aerospace Kev Lag Luam: Aluminium cov khoom tsis sib nqus muaj txiaj ntsig zoo rau kev lag luam aerospace, qhov twg cov ntaub ntawv uas tsis cuam tshuam nrog aircraft navigation systems yog nyiam.
• Cov cuab yeej kho mob: Aluminium is commonly used in medical devices that require compatibility with magnetic resonance imaging (MRI) tshuab.

Ntsuas cov hlau nplaum ntawm txhuas hauv tsev

Xav sim cov hlau nplaum ntawm txhuas koj tus kheej? Nov yog qhov kev sim yooj yim uas koj tuaj yeem sim hauv tsev:

1. Sau cov ntaub ntawv: Koj yuav xav tau lub zog neodymium hlau nplaum thiab ib daim ntawm txhuas, xws li cov khoom siv aluminium.
2. Txoj kev: Tuav cov hlau nplaum ze rau ntawm aluminium. Koj yuav pom tias aluminium tsis lo rau cov hlau nplaum.
3. Twist: Txav cov hlau nplaum sai sai rau ntawm txhuas, ces rub nws tseg. Koj tuaj yeem pom me ntsis thawb lossis rub ntawm lub txhuas. Cov tshuaj tiv thaiv no yog tshwm sim los ntawm induced currents hu ua eddy currents, uas tsim ib ntus magnetic teb nyob ib ncig ntawm lub txhuas.
