Yog, nws yog ua tau rau ib hlau nplaum ruaj khov rau poob nws hlau nplaum . Muaj peb txoj hauv kev rau qhov tshwm sim: 2) Los ntawm demagnetizing magnetic teb: hlau nplaum ruaj khov nthuav tawm tus yam ntxwv hu ua coercivity, uas yog lub peev xwm ntawm cov khoom siv los tiv thaiv kev demagnetized los ntawm kev siv magnetic teb.

Kuj tseem paub yog, cov hlau nplaum puas poob hlau nplaum lub sijhawm?

Demagnetization yog txheej txheem qeeb tab sis hlau nplaum yuav poob lawv lub zog dhau sijhawm . Qhov no feem ntau tshwm sim nyob rau hauv ob txoj kev. Yog li hu ua mus tas li hlau nplaum yog tsim los ntawm cov ntaub ntawv ua los ntawm magnetic domains, nyob rau hauv uas atoms muaj electrons uas nws spines ua ke nrog ib leeg.

Ib tug kuj yuav nug, ntev npaum li cas cov hlau nplaum nyob ruaj khov? A hlau nplaum ruaj khov , yog khaws cia thiab siv rau hauv kev ua haujlwm zoo, yuav khaws nws cov hlau nplaum rau xyoo thiab xyoo. Piv txwv li, nws yog kwv yees tias a neodymium hlau nplaum poob kwv yees li 5% ntawm nws cov hlau nplaum txhua 100 xyoo.

Ntxiv mus, vim li cas cov hlau nplaum ruaj khov poob nws cov hlau nplaum?

Cov hlau nplaum ruaj khov ua tau poob lawv hlau nplaum yog hais tias lawv poob los yog banged txaus los tsoo lawv cov thawj tawm ntawm kev sib raug zoo. Yog vim li cas uas yuav nyuaj rau pob ib daim hlau thiab ua nws magnetic vim tus txoj kev vibrations propagate nyob rau hauv tus khoom.

Cov hlau nplaum puas ua haujlwm tas mus li?

Theoritically ib hlau nplaum yuav muaj nws cov khoom sib nqus Mus ib txhis . Qhov no tshwm sim vim yog koj khaws ib hlau nplaum tsis tawm tsam nws lub zog sib nqus thiab ntawm qhov kub ntawm 0K ces nws yuav khaws nws lub zog sib nqus mus ib txhis.

Koj yuav ua li cas thiaj ua tau ib lub hlau nplaum ruaj khov?

Yog tias koj tuaj yeem pom cov hlau nplaum muaj zog heev, rov rub nws hla koj cov hlau nplaum uas tsis muaj zog. Cov hlau nplaum muaj zog yuav rov kho cov hlau nplaum hauv cov hlau nplaum tsis muaj zog [qhov chaw: Luminaltech]. Magnet stacking Ib txoj hauv kev ua kom cov hlau nplaum tsis muaj zog yog los ntawm kev sib tsoo ntau dua ua ke

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"

Puas yog cov pa roj tsis muaj qhov ruaj khov thiab ntim?

Cov roj yog ib yam khoom uas tsis muaj qhov ntim thiab tsis muaj qhov tseeb. Khoom thiab kua muaj ntim uas tsis hloov tau yooj yim. Ib qho roj, ntawm qhov tod tes, muaj qhov ntim uas hloov pauv kom haum rau qhov ntim ntawm nws lub thawv. Cov molecules nyob rau hauv ib tug roj yog sib nrug heev piv nrog rau cov molecules nyob rau hauv ib tug khoom los yog kua

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
