Kev siv cov hlau ntshiab hauv kev tsim cov hlau nplaum muaj ntau yam tseem ceeb. Cov hlau ntshiab, vim nws cov khoom sib nqus, yog cov khoom siv tseem ceeb hauv kev tsim cov hlau nplaum. Nov yog cov lus piav qhia ntxaws:
Cov hlau ntshiab feem ntau yog siv los ua cov khoom siv hauv paus rau kev tsim ntau hom hlau nplaum, tshwj xeeb tshaj yog cov uas xav tau kev ua haujlwm siab sib nqus. Nws cov yam ntxwv ferromagnetic muaj peev xwm tso cai rau nws yooj yim magnetized thiab khaws lub zog sib nqus, ua rau nws zoo tagnrho rau cov ntawv thov uas tsim nyog muaj zog sib nqus.
Hauv cov txheej txheem tsim khoom, cov hlau ntshiab tau txais kev kho mob tshwj xeeb los txhim kho nws cov khoom sib nqus. Cov kev kho mob no feem ntau suav nrog cua sov cov hlau mus rau qhov kub thiab txias thiab tom qab ntawd txias nws hauv qhov chaw tswj hwm kom ua kom cov hlau nplaum sib nqus hauv cov khoom siv.
Cov txheej txheem no, hu ua annealing, pab txhim kho kev sib nqus ntawm cov hlau.
Tsis tas li ntawd, cov hlau ntshiab yuav raug alloyed nrog lwm cov ntsiab lus, xws li npib tsib xee thiab cobalt, los tsim cov alloys xws li alnico, uas nthuav tawm txawm tias muaj zog sib nqus. Cov hlau nplaum no tau siv dav hauv kev tsim cov hlau nplaum ruaj khov rau cov ntawv thov xws li motors, generators, thiab ntau yam khoom siv hluav taws xob.
Ntxiv nrog rau kev siv cov ntaub ntawv alloyed, cov hlau ntshiab kuj yog siv los tsim cov hlau nplaum mos, uas yog siv hauv cov khoom siv hluav taws xob.
xws li transformers thiab inductors. Cov hlau nplaum mos yog tus cwj pwm los ntawm lawv lub peev xwm los ua kom yooj yim hlau nplaum thiab demagnetized, ua rau lawv haum rau cov ntawv thov uas yuav tsum tau hloov pauv sai hauv cov hlau nplaum.
Zuag qhia tag nrho, cov hlau ntshiab ua lub luag haujlwm tseem ceeb hauv kev tsim cov hlau nplaum, ob qho tib si raws li cov khoom siv ib leeg thiab ua ib feem hauv cov hlau nplaum sib nqus. Nws cov khoom sib nqus tshwj xeeb thiab muaj peev xwm ua tiav thiab kho kom txhim kho cov khoom no ua rau nws yog ib qho tseem ceeb hauv kev tsim cov hlau nplaum rau ntau yam kev siv.
