Thaum siv dej thiab zaub roj, daim ntawv clips txav los ntawm lub ua kua mus rau hlau nplaum sai heev. Qhov no yog vim qhov kua muab kev tiv thaiv tsawg heev. Txawm li cas los xij, daim ntawv clips hauv pob kws phoov tau maj mam txav mus rau qhov hlau nplaum . Cov hlau nplaum tseem tseem nyiam cov ntawv ntawv hauv txhua qhov xwm txheej.
Tsis tas li, cov hlau nplaum puas tuaj yeem rub los ntawm cov kua?
Cov hlau nplaum tuaj yeem rub los ntawm gases, zoo li cua, tab sis lawv ua tau kuj rub los ntawm khoom thiab txawm kua , nyob ntawm lub zog ntawm lub hlau nplaum . Ib qho chaw sib nqus yog qhov chaw nyob ib puag ncig hlau nplaum qhov twg nws tuaj yeem nyiam los yog tshem tawm tej yam.
Kuj Paub, cov hlau nplaum tuaj yeem khaws cov ntawv hlau hauv dej? Yog ob leeg hlau nplaum thiab ntawv clips nyob hauv dej , lawv yuav tsis nyiam ” Amy: “Kuv xav hlau nplaum yuav tsum tau nyob rau hauv cov huab cua, tab sis nws tsis muaj teeb meem yog hais tias tus daim ntawv clip yog. Txawm li cas los xij, thaum hlau nplaum nyob hauv dej , lawv ua hauj lwm txawv. Cov ntawv clips yuav yuav repelled los ntawm hlau nplaum ."
Tom qab ntawd, cov hlau nplaum puas cuam tshuam rau dej?
Nws tsis zoo li nws yuav yog magnetic tab sis nws hloov tawm dej , thiab txhua yam teeb meem, tuaj yeem pom cov khoom sib nqus yog tias koj muab tso rau hauv qhov loj txaus sib nqus. Dej yog me ntsis repelled los ntawm ib tug muaj zog heev hlau nplaum.
Sib nqus quab yuam dhau los ntawm cov roj?
Cov magnetic zog (los yog magnetism) tuaj yeem hla dhau nyias cov ntawv tsis- Sib nqus cov khoom xws li ntawv, iav lossis ntoo. Yog hais tias tib steel pob bearing poob rau hauv ib lub tank hlau ntim nrog roj , cov hlau nplaum sticks rau lub tank hlau. Qhov no yog vim hlau yog ib Sib nqus khoom.

Koj puas ntxiv cov kua qaub rau hauv lub hauv paus lossis lub hauv paus rau cov kua qaub?
Ntxiv cov kua qaub ua kom cov concentration ntawm H3O + ions hauv cov tshuaj. Ntxiv ib lub hauv paus txo cov concentration ntawm H3O + ions hauv cov tshuaj. Cov kua qaub thiab lub hauv paus zoo li cov tshuaj tiv thaiv. Yog hais tias lub hauv paus yog ntxiv rau cov kua qaub, cov tshuaj yuav tsis acidic thiab txav mus rau nruab nrab ntawm pH nplai
Cov hlau nplaum puas yuav lo rau galvanized hlau?
"Galvanized" tsuas yog txhais tau hais tias muaj cov zinc txheej sab nraud ntawm cov Hlau. Yog hais tias cov hlau ismagnetic pib nrog, ces nws tseem yuav sib nqus tom qab galvanizing. Txij li feem ntau tsis muaj laj thawj rau galvanizestainless hlau, cov lus teb yuav luag ib txwm "yog, galvanized steel yog sib nqus"
Cov hlau nplaum ruaj khov puas poob hlau nplaum?
Yog lawm, nws muaj peev xwm ua tau rau cov hlau nplaum ruaj khov kom poob nws cov hlau nplaum. Muaj peb txoj hauv kev rau qhov no tshwm sim: 2) Ntawm qhov demagnetizing magnetic teb: cov hlau nplaum tas mus li nthuav tawm cov yam ntxwv hu ua coercivity, uas yog lub peev xwm ntawm cov khoom siv los tiv thaiv demagnetized los ntawm kev siv magnetic teb
Cov qauv dab tsi thaum koj nchuav hlau filings nyob ib ncig ntawm cov hlau nplaum?
Thaum cov ntaub ntawv hlau tau nchuav ib ncig ntawm cov hlau nplaum, cov duab ntawm cov hlau nplaum raug ntes. Vim li cas qhov no tshwm sim? Tsis tas li ntawd, cov ntaub ntawv hlau no cais ua cov qauv pom tseeb ntawm cov kab
Vim li cas cov hlau ua hlau nplaum ruaj khov?
Thaum cov hlau tsis muaj hlau nplaum yog siv rau cov hlau nplaum, cov atoms nyob rau hauv nws rov kho lawv tus kheej nyob rau hauv ib yam uas tsim ib tug mus tas li hlau nplaum. Raws li cov atoms ua kom haum, lawv tsim ib qho chaw sib nqus uas tsis poob nws lub zog. Yuav kom tsim tau ib qho chaw sib nqus, ib qho khoom atoms yuav tsum tau ua kom zoo
