Hauv cov tshuab hluav taws xob niaj hnub,Kauj Ruam Hloov HloovUa si lub luag haujlwm tseem ceeb. Nws yog zoo li qab-tus-scenes tus hero, ntsiag to ua rau muaj kev kis tau zoo thiab kev faib hluav taws xob tsim nyog ntawm hluav taws xob.
I. Dab tsi yog ib qib hloov pauv
Ib kauj ruam hloov pauv yog cov khoom siv hluav taws xob uas ua haujlwm ntawm txoj hauv paus ntsiab lus ntawm indectromagnetic induction. Nws lub luag haujlwm tseem ceeb yog hloov cov hluav taws xob tsawg rau hauv cov hluav taws xob ntau. Nws feem ntau muaj ib tus hlau core, ib qho winding ua ntej, thiab muaj kev winding thib ob. Thaum lwm qhov kev sib tw tam sim no los ntawm kev sib nqus ntawm thawj lub ntsej muag, muaj kev sib cav sib nqus yog tsim hauv cov tub ntxhais hlau. Qhov no hloov sib nqus tiaj kis dhau los ntawm thawj qhov cua thiab lub winding thib ob tib lub sijhawm. Raws li cov hauv paus ntsiab lus ntawm indcrwmquet induction, lub tshuab hluav taws xob yog tsim txom nyob rau hauv theem ob uas muaj winding. Txij li thaum tus naj npawb ntawm lem ntawm theem nrab winding ntawm kauj ruam hloov hluav taws xob yog ntau dua li cov lus qhia ntawm thawj lub winding, yog li ua tiav qhov kev nce hluav taws xob ntau.
Ii. Rau cov tseem ceeb ntawm cov hloov pauv hloov
