Kev faib tawm los ntawm cov khoom siv
(1) Cov khoom siv hlau nplaum ruaj khov
Xws li cov khoom siv hlau nplaum tsis tshua muaj hauv ntiaj teb (NdFeB Nd2Fe14B), samarium cobalt (SmCo), Alnico (AlNiCo)
(2) Cov khoom siv hlau nplaum ruaj khov (Ferrite)
Kev faib tawm los ntawm kev tsim khoom
Raws li cov txheej txheem ntau lawm, nws tau muab faib ua: sintered ferrite, bonded ferrite, txhaj tshuaj ferrite, peb cov txheej txheem no tau muab faib ua vaj huam sib luag thiab anisotropic hlau nplaum raws li kev taw qhia ntawm cov hlau nplaum sib nqus.
Cov saum toj no yog cov khoom siv hlau nplaum ruaj khov nyob hauv kev ua lag luam tam sim no, thiab qee qhov tsis tuaj yeem siv dav vim cov txheej txheem tsim khoom lossis cov laj thawj vim li cas, xws li Cu-Ni-Fe (tooj liab-nickel-iron), Fe-Co-Mo ( hlau-cobalt molybdenum), Fe-Co-V (iron-cobalt vanadium), MnBi (manganese-bismuth)
