Cov hauv qab no yog peb txoj hauv kev los txhim kho cov khoom sib nqus ntawm cov hlau nplaum:
Rau ib lub voj voog hlau nplaum, ntxiv cov tub ntxhais hlau hauv qhov chaw tuaj yeem ntxiv dag zog rau nws cov hlau nplaum.
Cov txheej txheem ntawm kev tsom xam cov kab hlau nplaum tuaj yeem siv tau; los ntawm kev txuas cov hlau nplaum hluav taws xob rau cov hlau nplaum, lub zog hlau nplaum yuav raug tsim tawm ntawm cov npoo thiab cov fab ntawm cov phaj conductive.
Siv cov hlau nplaum los ua kom cov hlau nplaum.
Ua kom cov hmoov sib nqus cov ntsiab lus.
Ntxiv ib lub kauj thiab siv tam sim no kom muaj hlau nplaum.
Ua kom cov kab kab uas hla thiab cov xov tooj ntawm cov lem hauv electromagnet's coil; qhov ntau tig, qhov zoo.
