Magnet yog ib yam khoom siv dav thiab siv dav hauv peb lub neej txhua hnub. Nws muaj lub zog electrostatic thiab ib qho kev nqus zog, thiab tuaj yeem nqus tau qee yam khoom siv hlau. Tab sis dab tsi cuam tshuam rau lub zog rub ntawm lub hlau nplaum?
Ua ntej, cov duab ntawm cov hlau nplaum cuam tshuam rau tus nqi ntawm lub zog nws rub. Piv txwv li, rau cov pob hlau thiab cov ntsia hlau ntawm tib qhov loj, qhov nqus ntawm cov ntsia hlau yog ntau dua li cov khoom hlau. Vim li cas qhov no tshwm sim? Vim hais tias kev faib ntawm tus ntsia thawv magnetic teb yog sib xws thiab cov magnetic teb cuam tshuam rau lub ntiaj teb sab nraud me dua, lub zog nqus tau ntau dua.
Qhov thib ob, cov khoom siv ntawm cov hlau nplaum tseem yuav cuam tshuam nws lub zog rub. Rau cov hlau nplaum ntawm tib qhov loj, cov hlau nplaum uas muaj zog ferromagnetic muaj zog muaj zog dua li cov hlau nplaum uas muaj zog ferromagnetic zog. Vim hais tias cov hlau nplaum uas muaj zog ferromagnetic muaj ntau ferromagnetic atoms, lub zog ntawm sab nraud magnetic teb ntawm nws yog pom tseeb dua, yog li lub zog nqus ntau dua.
Thib peb, qhov chaw sib cuag ntawm cov hlau nplaum thiab cov khoom raug nyiam kuj tseem cuam tshuam rau qhov loj ntawm nws lub zog rub. Qhov loj dua ntawm qhov chaw sib cuag, lub zog nqus ntau dua. Qhov no yog vim hais tias cov hlau nplaum lub zog ntawm cov khoom raug attracted yog ntau yam, yog li lub zog nqus tau ntau dua.
Thaum kawg, dab tsi koj yuav tsum tau them sai sai rau thaum siv cov hlau nplaum yog qhov zoo ntawm cov hlau nplaum thiab qhov kev ncua deb ntawm cov hlau nplaum thiab cov khoom raug nyiam. Qhov loj ntawm cov hlau nplaum kuj muaj qee yam cuam tshuam rau qhov loj ntawm nws lub zog rub. Qhov loj dua, lub zog nqus ntau dua. Nyob rau tib lub sijhawm, qhov kev ncua deb ntawm cov hlau nplaum thiab cov khoom raug nyiam kuj cuam tshuam rau nws lub zog nqus. Qhov me me qhov kev ncua deb, lub zog nqus zog.
