Hlau nplaum txhais
Hlau nplaum ib yog ib yam twj paj nruas uas possesses thaj attracting tej yam, xws li hlau, vim tias muaj ib daim teb magnetic.
Qhov txawv ntawm haujlwm ruaj nrees hlau nplaum thiab Electromagnets
Tus hlau nplaum haujlwm ruaj nrees yog tsim los ntawm ferromagnetic ntaub, uas yog magnetized uas muaj zog lwm magnetic teb. Cov khoom tawv magnetically uas yog siv yuav ib feem ntawm nws txoj kev magnetization tom qab lwm magnetic teb yog muab tua. Feem ntau, magnetic teb tseem ceeb hauv lub sib nqus khoom tawg yooj yim. Txhua lwm magnetic tom teb yog nyob ze tug.
Hlau nplaum haujlwm ruaj nrees siv tau yooj yim designs uas tsis muaj txhua yam uas muab lub zog qhov sib nqus, thiab yuav tsis cuam tshuam dab tsi los ntawm cov hwjchim failures.
Electromagnets mas feem ntau yog nyob rau hauv daim hlau ntxhais solenoids. Electromagnets magnetic teb yog tsim los ntawm fais tam sim no nyob rau hauv ib lub kauj kua hlau thiab strengthened los ntawm ib tug tub ntxhais mos-hlau. Lub magnetism disappears thaum cov fais fab yuav muab tua.
