Magnets siv tau rau hauv qhov chaw … Tsis zoo li ntau lwm yam khoom koj tuaj yeem nqa mus rau qhov chaw uas xav tau cov cuab yeej ntxiv lossis cov cuab yeej siv los ua haujlwm, cov hlau nplaum yuav ua haujlwm yam tsis muaj kev pab ntxiv. Magnets tsis xav tau lub ntiajteb txawj nqus lossis cua. Hloov chaw, lawv lub zog los ntawm qhov chaw electromagnetic lawv tsim txhua yam los ntawm lawv tus kheej.
Cov hlau nplaum ua haujlwm ntawm lub hli?
Tam sim no, lub hli tsis muaj qhov sib nqus sab hauv raws li nws tuaj yeem pom hauv ntiaj teb Txawm li cas los xij, muaj cov cheeb tsam hauv cheeb tsam ntawm nws qhov chaw txog li ob peb puas kilometers nyob qhov twg muaj zog magnetic teb prevails. Qhov no tau tshwm sim los ntawm kev ntsuas ntawm pob zeb los ntawm Apollo missions.
Pob hlau nplaum ua haujlwm hauv lub tshuab nqus tsev?
Cov hlau nplaum ua haujlwm zoo kawg nkaus hauv lub tshuab nqus tsev- thiab thaum tsis muaj qhov gravitational. Lawv tsis nyob ntawm ib qho "ib puag ncig" lossis "nruab nrab". Thiab lub zog electromagnetic yog ywj siab ntawm lub ntiajteb txawj nqus, ib yam nkaus.
Cov hlau nplaum ua haujlwm hauv qab dej puas cov hlau nplaum ua haujlwm hauv qhov chaw?
Dej yuav luag tsis muaj hlau nplaum, yog li hlau nplaum ua haujlwm hauv qab dej tib yam li lawv ua hauv huab cua lossis hauv lub tshuab nqus tsev. Magnets koom nrog quab yuam.
Cov hlau nplaum ua haujlwm hauv Mars?
Tsis zoo li lub ntiaj teb, Mars tsis muaj lub ntiaj teb sib nqus teblos tiv thaiv nws los ntawm kev nruj ntawm qhov chaw huab cua - tab sis nws muaj qhov chaw hauv zos, induced magnetism. Tam sim no, cov kws tshawb fawb muaj peev xwm tsim tau ib daim ntawv qhia zoo kawg, cov ncauj lus kom ntxaws txog cov hluav taws xob tam sim no uas yog lub luag haujlwm rau shaping cov magnetic teb.

Puas yog cov hlau nplaum ua los ntawm cov hlau nplaum?
Natural magnets muaj nyob rau hauv lub ntiaj teb thiab yog nplua nuj nyob rau hauv ib tug hlau ntxhia hu ua magnetite. Cov hlau nplaum uas tsim los ntawm tib neeg tau tsim nyob rau hauv ib lub chaw sim los ntawm kev noj cov hlau alloys thiab ua lawv kom haum rau tus nqi .
Puas yog cov hlau nplaum muaj zog dua li cov hlau nplaum ruaj khov?
Electromagnets muaj txiaj ntsig tseem ceeb ntawm kev tswj hwm lawv lub zog sib nqus - ob qho tib si los ntawm kev tig cov hlau nplaum rau lossis tawm thiab los ntawm kev kho qhov tam sim no. Lawv kuj tseem muaj rub lub zog ntau dua li cov hlau nplaum ruaj khov Qee qhov kev kwv yees tso cov hlau nplaum loj tshaj plaws ntawm 20 npaug zog dua li cov hlau nplaum ruaj khov .
Koj puas tuaj yeem khov cov nplaum nplaum nplaum nplaum nplaum?
Yog, koj tuaj yeem khov cov nplaum nplaum nplaum nplaum rau ib ncig ntawm 3 lub hlis. Koj tuaj yeem khov cov nplaum nplaum nplaum nplaum nplaum uas tsis tau ci los yog ci uas txhais tau tias koj tuaj yeem khov cov khoom seem ntawm cov paj npleg.
Puas yog nplawm nplaum nplaum nplaum?
Y Whipped cream yog a colloid. Nws muaj cov roj hauv cov kua, yog li nws yog npuas. Sol yog ib qho kev ncua colloidal nrog cov khoom hauv cov kua . hom tshuaj twg yog nplawm nplaum? Chemistry of Cream Whipped cream is a foam-a suspension of gas bubbles in other substance.
Vim li cas ib yam khoom hlau tsis muaj hlau nplaum nyiam rau cov hlau nplaum?
Thaum cov hlau nplaum raug coj los ze rau cov khoom siv ferromagnetic yav dhau los uas tsis muaj hlau nplaum, nws ua rau cov hlau nplaum hauv zos ntawm cov khoom uas tsis zoo li cov ncej ze tshaj, ib yam li hauv. unmagnetized khoom rau cov hlau nplaum raws li daim duab hauv .
