Yog li ib yam hlau nplaum yuav maj mam qis dua lub sijhawm. … Lub coil lub zog magnetic teb ua rau thaj chaw microscopic nyob rau hauv cov hlau siv lead ua, hu ua magnetic domains, line up their magnetism with each other. Qhov no ua rau muaj zog tshiab hlau nplaum. Thaum siv txhua hnub, cov hlau nplaum yuav poob thiab banged txog.

Yuav siv sijhawm ntev npaum li cas rau cov hlau nplaum kom poob nws lub zog?

Qhov kev sib raug zoo no raug puas ntsoog thaum lub sijhawm, feem ntau yog vim qhov tshwm sim ntawm tshav kub thiab tsis muaj zog electromagnetic teb, thiab qhov no ua rau cov qib ntawm cov hlau nplaum tsis muaj zog. Cov txheej txheem qeeb heev, txawm li cas los xij: niaj hnub samarium-cob alt hlau nplaum yuav siv sij hawm ncig 700 xyoo kom poob ib nrab ntawm nws lub zog.

Cov hlau nplaum feem ntau kav ntev npaum li cas?

Yog li kuv lub hlau nplaum ruaj khov yuav kav ntev npaum li cas? Koj cov hlau nplaum tas mus li yuav tsum poob tsis ntau tshaj 1% ntawm nws lub zog sib nqus nyob rau lub sijhawm 100 xyoo muab nws tau teev thiab saib xyuas kom raug. Muaj ob peb yam uas yuav ua rau koj cov hlau nplaum poob nws lub zog: HEAT.

Pob hlau nplaum degrade overtime?

Yog, hlau nplaum tsis muaj zog thaum lub sijhawm, tab sis nyob ntawm qhov kev hlub ntawm nws, nws yuav khaws nws cov hlau nplaum tseem ceeb mus ib txhis. … Kub kub, stray magnetic teb, hluav taws xob tam sim no, hluav taws xob, av noo, thiab kev puas tsuaj tuaj yeem demagnetize cov hlau nplaum, tab sis nyob ntawm seb hom hlau nplaum, feem ntau nws yuav kav ntev.

Ib tug hlau nplaum ruaj khov puas poob nws lub zog?

Yes, nws yogua tau rau cov hlau nplaum tas mus li poob nws cov hlau nplaum. … Nrog rau qhov muaj zog txaus magnetic teb ntawm qhov sib txawv polarity, nws muaj peev xwm demagnetize cov hlau nplaum [txawm qhov no los ntawm lwm cov hlau nplaum ruaj khov, lossis lub solenoid].
