Kev nkag siab zoo, ntau tus neeg paub tias cov khoom sib nqus ntawm cov hlau nplaum muaj zog muaj zog heev, tshwj xeeb tshaj yog cov hlau nplaum loj loj, yooj yim rau cov neeg mob thaum siv. Yog li tam sim no piav qhia yuav ua li cas cov hlau nplaum muaj zog tuaj yeem tshem tawm cov hlau nplaum?
Qhov tseeb, txoj kev ua tau yooj yim heev, cov hlau nplaum muaj zog yog qhov kub thiab txias hauv qab 80 degrees, tom qab ntawd peb tsuas yog muab cov hlau nplaum muaj zog rau ntawm qhov hluav taws kub rau ob peb feeb, kom txias los ntawm muab tso rau ntawm ib sab ntawm cov hlau, pom tias nws tau ploj lawm. magnetism, tsis nqus li. Qhov laj thawj yog vim li cas cov hlau nplaum muaj zog yog hlau nplaum yog vim cov hlau atoms hauv cov hlau nplaum muaj zog tau teem rau hauv kev txiav txim tsis tu ncua. Tom qab nws tau rhuab, thawj qhov kev npaj ntawm hlau atoms yuav tsis zoo, yog li nws poob nws cov khoom qub hlau nplaum.
Yuav ua li cas tuav thiab khaws cov hlau nplaum kom zoo?
Nco ntsoov ceev faj, vim tias cov hlau nplaum yuav adsorb lawv tus kheej ua ke, ces muaj kev pheej hmoo ntawm pinching koj cov ntiv tes. Cov hlau nplaum kuj tseem tuaj yeem ua rau cov hlau nplaum nws tus kheej vim yog kev sib tsoo thaum lawv txuas rau ib leeg, ua rau lub kaum sab xis tawg lossis tawg, thiab lwm yam. Tom qab ntawd, khaws cov hlau nplaum kom deb ntawm cov khoom uas yooj yim magnetized, xws li floppy disks, credit cards. , khoos phis tawj saib, saib, xov tooj ntawm tes, khoom siv kho mob, thiab lwm yam.
Rau cov hlau nplaum loj dua, cov yas lossis cov duab los qhia yuav tsum tau ntxiv ntawm txhua daim kom paub meej tias cov hlau nplaum tuaj yeem sib cais tau yooj yim. Cov hlau nplaum yuav tsum muab cia rau hauv qhov chaw qhuav, qhov kub thiab txias kom ntau li ntau tau.
Yog li peb yuav ua li cas sib nqus sib cais?
Tsuas yog cov khoom siv ua raws li cov hlau nplaum tuaj yeem ua lub luag haujlwm hauv kev sib cais ntawm cov hlau nplaum, thiab cov khoom tuab dua, qhov zoo dua qhov kev sib nqus sib nqus.
Cov lus ceeb toom ntawm kev siv cov hlau nplaum muaj zog:
1. Cov hlau nplaum yuav maj mam txo lub zog nqus hauv cov txheej txheem ntawm kev siv lub sijhawm ntev.
2. Ua tib zoo saib xyuas qhov zoo thiab qhov tsis zoo ntawm cov hlau nplaum, lawv yuav tsum tsis txhob cuam tshuam ib leeg hauv kev siv, txwv tsis pub nws yog qhov nyuaj rau kev sib cais.
3. Cov hlau nplaum muaj zog tsis haum rau kev sib cuag ncaj qha nrog hlau thiab lwm yam khoom siv xeb, yooj yim rau xeb, kev kho deg lossis txheej txheej yuav tsum tau ua.
