Tej zaum feem ntau tseem ceeb feature ntawm lub ntiaj teb magnetic teb yog tias nws tiv thaiv peb ntawm lub hnub lub hnub ci cua thiab hluav taws xob. Magnets kuj tuaj yeem tsim los ntawm kev siv hluav taws xob. Los ntawm wrapping ib tug hlau nyob ib ncig ntawm ib tug hlau bar thiab khiav tam sim no los ntawm cov hlau, muaj zog heev hlau nplaum tsim tau.
Xav txog qhov no, cov hlau nplaum siv li cas rau cov menyuam yaus?
Cov me nyuam tuaj yeem muaj kev lom zem thaum kawm txog ntau yam thiab tseem ceeb siv ntawm hlau nplaum hauv ntiaj teb ib ncig ntawm lawv. Feem ntau siv ntawm hlau nplaum suav nrog lub compass, vending machines, tub yees hlau nplaum thiab hluav taws xob motors. Qee hom tsheb ciav hlau txawm levitate saum cov hlau nplaum sib nqus!
Qhov thib ob, lub ntiaj teb zoo li lub hlau nplaum rau cov menyuam li cas? Peb Lub ntiaj teb yog a nyiam ib qho loj hlau nplaum nrog ib tug kua hlau core tob hauv nws uas tig, tsim ib Sib nqus teb nrog North thiab South Ncej. Lub teb muaj zog tshaj ntawm cov ncej tiag. Lub hnub kuj heev Sib nqus.
Ib yam li ntawd, nws raug nug, vim li cas hlau nplaum tseem ceeb?
Maxwell tau qhia ua lej yuav ua li cas hloov pauv magnetic teb tsim ib qho kev hloov hluav taws xob (thiab vice versa). Yog li ntawd, hlau nplaum yog heev tseem ceeb vim peb siv nws los tsim hluav taws xob. Qhov tseeb, feem ntau ntawm lub zog uas peb siv niaj hnub no los ntawm cov hlau nplaum tig (saib hauv qab).
Vim li cas cov hlau nplaum tseem ceeb rau lub neej txhua hnub?
Magnets yog siv los ua kom nruj nruj ntawm lub qhov rooj rau lub tub yees thiab lub tub yees. Lawv muaj hwj chim hais lus nyob rau hauv stereos, earphones, thiab TVs. Magnets yog siv los khaws cov ntaub ntawv hauv computer, thiab yog tseem ceeb hauv cov tshuab scanning hu ua MRIs (magnetic resonance imagers), uas cov kws kho mob siv los saib hauv tib neeg lub cev.

Cov pa oxygen txhais li cas rau cov menyuam yaus?
Cov me nyuam txhais cov pa oxygen: ib qho tshuaj muaj nyob rau hauv cov huab cua uas tsis muaj xim tsis muaj ntxhiab tsw tsw uas tsim nyog rau lub neej. oxygen
Vim li cas qhov tseem ceeb ntawm qhov tseem ceeb?
Thaum koj pom tus nqi kiag li hauv qhov teeb meem lossis qhov sib npaug, nws txhais tau hais tias txhua yam nyob hauv tus nqi tiag tiag yog qhov zoo. Cov txiaj ntsig tsis zoo feem ntau siv rau hauv cov teeb meem cuam tshuam nrog kev nyob deb thiab qee zaum siv nrog qhov tsis sib xws. Qhov ntawd yog qhov tseem ceeb uas yuav tsum nco ntsoov nws zoo li qhov deb ntawm xoom
Cov hlau nplaum ruaj khov puas poob hlau nplaum?
Yog lawm, nws muaj peev xwm ua tau rau cov hlau nplaum ruaj khov kom poob nws cov hlau nplaum. Muaj peb txoj hauv kev rau qhov no tshwm sim: 2) Ntawm qhov demagnetizing magnetic teb: cov hlau nplaum tas mus li nthuav tawm cov yam ntxwv hu ua coercivity, uas yog lub peev xwm ntawm cov khoom siv los tiv thaiv demagnetized los ntawm kev siv magnetic teb
Vim li cas cov nuj nqis tseem ceeb tseem ceeb thaum qhia txog kev ntsuas?
Cov duab tseem ceeb yog qhov tseem ceeb los qhia qhov tseeb ntawm koj cov lus teb. Qhov no yog qhov tseem ceeb hauv kev tshawb fawb thiab engineering vim tias tsis muaj cov cuab yeej ntsuas tuaj yeem ua qhov ntsuas nrog 100% precision. Siv cov nuj nqis tseem ceeb tso cai rau tus kws tshawb fawb paub tias cov lus teb meej npaum li cas, lossis qhov tsis paub meej npaum li cas
Vim li cas cov hlau ua hlau nplaum ruaj khov?
Thaum cov hlau tsis muaj hlau nplaum yog siv rau cov hlau nplaum, cov atoms nyob rau hauv nws rov kho lawv tus kheej nyob rau hauv ib yam uas tsim ib tug mus tas li hlau nplaum. Raws li cov atoms ua kom haum, lawv tsim ib qho chaw sib nqus uas tsis poob nws lub zog. Yuav kom tsim tau ib qho chaw sib nqus, ib qho khoom atoms yuav tsum tau ua kom zoo
