Cov hlau nplaum thiab cov hlau nplaum ruaj khov yog ob lub ntsiab lus sib txawv.
Cov hlau nplaum xa mus rau cov hlau lossis hlau cov ntaub ntawv uas tuaj yeem tswj tau cov hlau nplaum muaj zog tom qab kho. Nws muaj qee yam sib nqus permeability thiab magnetization lub zog, yog li nws tau dav siv hauv kev tsim cov khoom siv hluav taws xob xws li lub taub hau sib nqus, motors thiab transformers. Kev tsim cov hlau nplaum txais kev kho lub cev, xws li cua sov thiab cua txias.
Cov hlau nplaum tas mus li hais txog cov ntaub ntawv uas tuaj yeem tswj tau cov hlau nplaum muaj zog txawm tias tsis muaj qhov sib nqus sab nraud. Lub hauv paus ntawm nws cov hlau nplaum yog lub tshuab hluav taws xob sib nqus ntawm cov khoom nws tus kheej. Cov hlau nplaum tas mus li yog cov khoom sib nqus tshwj xeeb nrog cov hlau nplaum ntev thiab ruaj khov, yog li lawv tau siv dav hauv kev tsim cov motors, disk drives thiab lwm yam khoom siv.
Txawm hais tias cov hlau nplaum thiab cov hlau nplaum tas mus li txawv ntawm lub cev, kev tsim tshuab thiab daim ntawv thov, lawv ob leeg muaj qhov tseem ceeb ntawm daim ntawv thov kev lag luam. Ob lub hlau nplaum thiab cov hlau nplaum ruaj khov tuaj yeem muab kev yooj yim thiab cov txiaj ntsig rau tib neeg kev tsim khoom thiab lub neej.
Raws li keeb kwm ntawm niaj hnub kev lag luam kev loj hlob thiab kev tshawb fawb thiab thev naus laus zis, daim ntawv thov thiab kev loj hlob zeem muag ntawm cov hlau nplaum thiab cov hlau nplaum ruaj khov yog dav dua. Hauv kev tsim khoom, kev thauj mus los, kev sib txuas lus thiab lub zog tshiab, kev siv cov ntaub ntawv no tseem yuav ua lub luag haujlwm tseem ceeb. Ntxiv mus, raws li tib neeg txoj kev paub txog kev txhim kho kom ruaj khov txuas ntxiv mus ntxiv, kev siv cov hlau nplaum hlau nplaum thiab cov hlau nplaum ruaj khov yuav muaj nuj nqis ntxiv. Nws ntseeg tau tias cov hlau nplaum hlau nplaum thiab cov hlau nplaum ruaj khov siv rau hauv kev tsim khoom thiab kev tshawb fawb tshawb fawb yuav txuas ntxiv txhim kho thiab txhim kho, ua rau muaj kev xav tsis thoob thiab nce ntxiv rau tib neeg.
Txawm hais tias cov hlau nplaum hlau nplaum thiab cov hlau nplaum ruaj khov yog ob lub ntsiab lus sib txawv, lawv yog ob qho tib si tseem ceeb ntawm cov khoom sib nqus thiab tseem yuav ua lub luag haujlwm zoo hauv tib neeg kev tsim khoom thiab lub neej. Peb yuav tsum txuas ntxiv tshawb nrhiav thiab coj mus rhaub cov peev txheej ntawm cov khoom siv hlau nplaum, txhawb lawv txoj kev loj hlob, thiab txhawb kev sib raug zoo thiab kev vam meej.
