Dab tsi yog cov khoom siv sib nqus (cov khoom siv sib nqus)

Tom qab tau tsim lub zog, cov khoom siv hlau nplaum ruaj khov tseem khaws nws cov hlau nplaum tom qab tshem tawm cov chaw sib nqus sab nraud. Nws qhov kev ua tau yog tus cwj pwm los ntawm kev siab siab thiab kev coercivity siab. Cov yam ntxwv no tuaj yeem siv los ua cov hlau nplaum tas mus li, uas tuaj yeem siv los ua cov khoom sib nqus. Xws li cov koob sib xws, cov ntsuas, micro tsheb, lub cev muaj zog, cov kab xev kaw suab, xov tooj thiab kev kho mob. Cov ntaub ntawv cov hlau nplaum ruaj khov muaj xws li ferrite thiab hlau cov hlau nplaum ruaj khov.

Ferrites siv nyob rau hauv ntau, yog siv dav, thiab tsis tshua muaj nqi, tab sis lawv muaj cov khoom sib nqus dav dav thiab siv rau cov hlau nplaum tas mus li feem ntau xav tau.

Ntawm cov hlau ruaj ruaj cov hlau nplaum cov ntaub ntawv, cov pa roj carbon hlau tau siv thawj zaug, tab sis nws cov khoom sib nqus tsis zoo. Cov ntau yam ntawm kev ua tau zoo ntawm cov khoom siv hlau nplaum tas li suav nrog cov tooj hlau nickel cobalt (Al-Ni-Co) thiab hlau chromium cobalt (Fe-Cr-Co); tsis tshua muaj lub ntiaj teb cov hlau nplaum tsis tu ncua, xws li lub ntiaj teb tsis tshua muaj cobalt (Re-Co) alloys (cov hom loj yog SmCo5 thiab Sm2Co17 ua los ntawm hmoov metallurgy tshuab tau dav siv neodymium hlau boron (Nd-Fe-B) lub ntiaj teb tsis tshua muaj hlau nplaum, neodymium hlau boron hlau nplaum tsis tsuas yog muaj kev ua tau zoo heev, tab sis kuj tsis muaj cov khoom tsis tshua muaj cobalt, yog li lawv dhau los ua kev ua haujlwm siab ruaj khov cov khoom siv hlau nplaum Cov neeg sawv cev ntawm, tau siv rau hauv kev hais lus siab, hluav taws xob hauv cov dej, nuclear hluav taws xob resonance meters, lub cev muaj zog me me, tsheb pib tsav tsheb, thiab lwm yam.
