Ib yam khoom tuaj yeem ua tau magnetized yog tias tag nrho nws cov khoom sib nqus sib nqus hauv cov ntaub ntawv feem ntau cov khoom siv me me, nyob ib ncig ntawm 10 - 4 - 10-6 m. https://en.wikipedia.org › wiki › Magnetic_domain
Magnetic domain - Wikipedia
tuaj yeem ua raws. … Tsuas yog qee yam khoom siv, hu ua ferromagnetic cov ntaub ntawv, tuaj yeem ua hlau nplaum. Lawv suav nrog hlau, cob alt, thiab npib tsib xee. Cov khoom uas tau raug hlau nplaum yuav dhau los ua cov hlau nplaum ib ntus lossis ruaj khov.
Cov ntaub ntawv dab tsi tsis tuaj yeem sib nqus?
Cov ntaub ntawv uas tsis nyiam los ntawm cov hlau nplaum yog hu ua cov khoom tsis sib nqus. Txhua yam khoom uas tsis yog hlau, npib tsib xee, thiab Cob altyog cov khoom tsis sib nqus xws li yas, roj hmab, dej, thiab lwm yam yog cov khoom tsis sib nqus. Cov khoom tsis sib nqus tsis tuaj yeem sib nqus.
Txhua cov ntaub ntawv puas tuaj yeem ua hlau nplaum?
cov khoom sib nqus yog ib txwm ua los ntawm hlau, tab sis tsis yog txhua yam hlau yog hlau nplaum. Hlau yog hlau nplaum, yog li txhua yam hlau nrog hlau nyob rau hauv nws yuav raug attracted rau ib tug hlau nplaum. Hlau muaj hlau, yog li daim ntawv hlau steel yuav raug nyiam rau cov hlau nplaum ib yam nkaus. Feem ntau lwm yam hlau, piv txwv li txhuas, tooj liab thiab kub, tsis yog hlau nplaum.
Cov ntaub ntawv tsis sib nqus puas tuaj yeem ua tau hlau nplaum?
Ntawm 91 cov hlau paub, tsuas yog peb qhov sib nqus tiag tiag ntawm chav sov: hlau, cob alt thiab nickel. Thaum cov buckyballs sib xyaw cov hlau, qee qhovelectrons raug tshem tawm - tso cai rau cov hlau kov yeej Stoner Criterion thiab ua tiav cov hlau nplaum. …
Koj puas tuaj yeem tsim tau dab tsi?
Magnetism tshwm sim ntawm qib subatomic tab sis tuaj yeem pom nws tus kheej ntawm cov nplai loj heev. Ferromagnetic cov ntaub ntawv, uas muaj xws li hlau, cob alt thiab npib tsib xee, yog cov ntaub ntawv uas nthuav tawm cov khoom sib nqus. … Koj tuaj yeem tsim cov khoom no thiab lwm yam khoom ferromagnetic los ntawm kev nthuav tawm lawv mus rau qhov chaw sib nqus uas twb muaj lawm.

Pob hlau nplaum puas lo rau cov hlau nplaum?
Magnets lo rau cov hlau uas muaj zog sib nqus lawv tus kheej, xws li hlau thiab npib tsib xee. Cov hlau tsis muaj zog hlau nplaum muaj xws li txhuas, tooj dag, tooj liab thiab txhuas. Yuav ua li cas cov hlau nplaum lo rau cov yeeb nkab hlau?
Yuav tsum nplawm nplaum nplaum nplaum?
Chunky Thaum Ntxov Thaum lub sij hawm koj cov nplaum yuav tshwm zoo kawg nkaus thaum koj ncuav rau hauv lub tais sib tov, tab sis ua chunky los yog grainy thaum nws nplawm. Qhov no kuj zoo ib yam, txawm tias nws tsis yog xov xwm zoo thaum nws tshwm sim.
Puas yog cov hlau tsis muaj hlau nplaum?
Feem ntau ntawm cov hlau tsis muaj steel hauv pawg no yog sib nqus. Yog tias muaj hlau, cov qauv siv lead ua ntawm martensitic stainless hlau tuaj yeem yog ferromagnetic. Vim hlau yog cov khoom tseem ceeb hauv cov hlau tsis muaj steel, martensitic steels muaj cov khoom sib nqus.
Yuav ua li cas yog cov hlau tsis muaj hlau nplaum?
Yuav ua li cas yog ib daim hlau uas tsis muaj hlau nplaum txawv ntawm tib daim hlau thaum nws yog hlau nplaum? Magnetic domains yog random oriented nyob rau hauv unmagnetizedhlau, raws li nyob rau hauv magnetized hlau. … -Lub North Ncej ntawm ib tug hlau nplaum yog lub npe tom qab "
Puas yog daim nplaum nplaum nplaum nplaum?
Scotch® Siv dav Daim Ntawv Ncauj Ncaujtuav rau qhov chaw ntev txog 3 hnub thiab tom qab ntawd tshem tawm tau yooj yim yam tsis muaj cov nplaum nplaum tom qab. Zoo heev rau daim ntawv lo, ntim khoom, thiab daim ntaub npog ntsej muag rau ntawm qhov chaw uas tsis muaj kev puas tsuaj.
