Cov tub yees Magnets yog dab tsi?

Fridge hlau nplaum, raws li lub npe qhia, yog cov ntawv nplaum me me uas txuas rau lub tub yees. Txawm li cas los xij, lawv puas yog hlau nplaum tiag? Cia wb mus saib tob rau lo lus nug no.
Ua ntej, nkag siab txog kev tsim cov tub yees hlau nplaum. Fridge hlau nplaum feem ntau muaj cov yas los yog hlau puag thiab ib daim ntawm cov khoom sib nqus. Cov khoom siv hlau nplaum feem ntau yog neodymium hlau boron hlau nplaum, uas yog cov hlau nplaum ruaj khov uas paub txog niaj hnub no. Cov hlau nplaum no sib txawv hauv cov duab thiab qhov loj me kom tau raws li cov qauv tsim ntawm cov khoom sib txawv. Txawm li cas los xij, cov hlau nplaum no lawv tus kheej tsis yog tag nrho cov hlau nplaum tub yees.
Qhov tseeb, qhov nplaum ntawm lub tub yees hlau nplaum los ntawm cov khoom siv hauv paus. Cov khoom siv hauv paus no feem ntau yog cov nplaum uas tuaj yeem kho cov khoom sib nqus hauv qhov chaw thiab ua kom nws nplaum. Thaum peb nplaum cov hlau nplaum tub yees rau ntawm lub tub yees, cov nplaum nplaum yuav txhim kho cov hlau nplaum ntawm lub tub yees ntawm lub qhov rooj tub yees, thaum cov khoom siv hlau nplaum yog lub luag haujlwm ruaj khov rau cov hlau nplaum lub tub yees rau lub tub yees.

Yog li, vim li cas cov hlau nplaum tub yees tuaj yeem adsorbed ntawm lub tub yees? Qhov no muaj feem xyuam rau txoj hauv kev ua haujlwm ntawm cov khoom sib nqus. Cov khoom siv hlau nplaum muaj cov cuab yeej ntawm kev nyiam cov khoom hlau, uas yog qhov peb feem ntau hu ua "magneticism". Thaum peb nqa lub tub yees hlau nplaum ze rau ntawm lub qhov rooj tub yees, cov khoom siv hlau nplaum yuav tsim kev nyiam nrog cov hlau hauv lub qhov rooj tub yees, yog li adsorbing lub tub yees hlau nplaum ntawm lub tub yees.
Qee tus neeg yuav xav tias lub tub yees hlau nplaum yog cov hlau nplaum, tab sis qhov tseeb nws tsis yog. Txawm hais tias lub tub yees hlau nplaum muaj cov khoom sib nqus, nws cov nplaum los ntawm cov khoom siv hauv paus. Tsuas yog thaum cov khoom siv hauv paus cuam tshuam nrog cov khoom siv hlau nplaum tuaj yeem txuas cov hlau nplaum rau lub tub yees kom ruaj khov. Yog li ntawd, peb tuaj yeem txiav txim siab tias lub tub yees hlau nplaum tsis yog cov hlau nplaum ua tiav, tab sis cov khoom tshwj xeeb uas muaj cov khoom sib nqus thiab cov khoom siv hauv paus.
