Thaum ib tug nonmagnetic daim ntawm steel yog siv rau a hlau nplaum , cov atoms nyob rau hauv nws rearrange lawv tus kheej nyob rau hauv ib tug yam uas tsim ib tug hlau nplaum ruaj khov . Raws li cov atoms ua aligned, lawv tsim ib Sib nqus teb uas tsis poob nws lub zog. Yuav kom tsim tau ib Sib nqus teb, ib yam khoom lub atoms yuav tsum tau oriented kom zoo.
Ib yam li ntawd, vim li cas cov hlau siv los ua cov hlau nplaum ruaj khov?
Hlau yog nyiam rau ua cov hlau nplaum ruaj khov hos soft hlau yog nyiam rau ua electromagnets. Txij li thaum, hlau muaj qhov tseem ceeb ntawm coercivity, nws yog nyiam rau ua cov hlau nplaum ruaj khov . Mos hlau yog siv rau ua electromagnets vim nws siab permeability thiab kuj, hysteresis voj yog nqaim.
Ib yam li ntawd, cov khoom siv twg yog siv los ua cov hlau nplaum ruaj khov thiab vim li cas? Cov hlau nplaum tas mus li yog tsim los ntawm "nyuaj" ferromagnetic cov ntaub ntawv xws li alnico ua thiab ferrite uas raug rau tshwj xeeb ua nyob rau hauv ib tug muaj zog magnetic teb thaum lub sij hawm tsim khoom kom haum lawv cov microcrystalline qauv, ua rau lawv nyuaj heev rau demagnetize.
Tsis tas li ntawd, cov hlau nplaum ruaj khov tsim li cas?
Txoj kev tseem ceeb ntawd hlau nplaum ruaj khov yog tsim yog los ntawm cua sov cov khoom siv ferromagnetic rau qhov kub siab tseem ceeb. Qhov kub yog qhov tshwj xeeb rau txhua hom hlau tab sis nws muaj qhov cuam tshuam ntawm kev sib dhos thiab "kho" cov thawj ntawm cov hlau nplaum hauv a ruaj khov txoj hauj lwm.
Vim li cas nws nyuaj rau magnetize steel?
Hlau muaj tsawg permeability. Li no nyob rau hauv ib tug sab nraud magnetic teb, nws yog heev nyuaj rau magnetize . Li no hlau yog khaws cia rau hauv ib qho chaw sib nqus sab nraud rau lub sijhawm ntev kom nws tuaj yeem tau txais cov khoom sib nqus thiab ua raws li cov hlau nplaum.

Vim li cas cov khoom muaj qhov ruaj khov thiab ntim?
1 Teb. Cov khoom muaj qhov ruaj khov thiab nyob hauv ib lub ntim ruaj khov. Vim hais tias cov khoom nyob rau hauv cov kua yog sib ze heev (Ntsuas ntxiv sib nrug tshaj nyob rau hauv cov khib nyiab) cov kua tsis yooj yim compress, yog li lawv ntim yog tsau. Gases kuj tuaj yeem ntws, yog li tuav cov duab ntawm lawv lub thawv tag nrho
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 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
Yam khoom twg tsis muaj qhov ruaj khov thiab tsis muaj qhov ntim ruaj khov?
Cov theem ntawm cov teeb meem uas tsis muaj qhov ntim ruaj khov thiab tsis muaj qhov ruaj khov yog cov roj. Cov roj tsis muaj qhov ruaj khov
Vim li cas cov hlau nplaum tseem ceeb rau cov menyuam yaus?
Tej zaum qhov tseem ceeb tshaj plaws ntawm lub ntiaj teb magnetic teb yog tias nws tiv thaiv peb ntawm lub hnub ci cua thiab hluav taws xob. Cov hlau nplaum kuj tuaj yeem tsim los ntawm kev siv hluav taws xob. Los ntawm wrapping ib tug hlau nyob ib ncig ntawm ib tug hlau bar thiab khiav tam sim no los ntawm cov hlau, cov hlau nplaum muaj zog heev tuaj yeem tsim tau
