Cov hlau nplaum yog thaj tsam ib ncig ntawm cov hlau nplaum uas muaj lub zog sib nqusTag nrho cov hlau nplaum muaj sab qaum teb thiab sab qab teb. Cov ncej sab nraud yog nyiam ib leeg, thaum tib tus ncej ntxeev ib leeg. … Thaum hluav taws xob khiav los ntawm ib lub kauj hlau, nws tsim ib qho chaw sib nqus.
Puas yog hlau nplaum thiab magnetic teb tib yam?
Nco ntsoov tias cov hlau nplaum yog cov khoom siv los yog cov khoom uas tsim cov hlau nplaumCov hlau nplaum no tsis pom tab sis yog lub luag haujlwm rau cov khoom tseem ceeb tshaj plaws ntawm cov hlau nplaum: lub zog uas rub ntawm lwm yam ntaub ntawv ferromagnetic, xws li hlau, thiab attracts los yog repels lwm yam hlau nplaum.
Puas yog cov hlau nplaum tsim los ntawm cov hlau nplaum?
Cov hlau nplaum sib txawv vim tias cov molecules hauv cov hlau nplaum tau teeb tsa kom lawv cov electrons tig mus rau tib txoj kev. Qhov kev npaj thiab kev txav no tsim ib lub zog sib nqus uas ntws tawm ntawm tus ncej sab qaum teb thiab los ntawm tus ncej sab qab teb. Lub zog sib nqus no tsim ib thaj chaw sib nqus nyob ib ncig ntawm cov hlau nplaum.
Magnetic teb yog dab tsi?
Sib nqus teb yog tsim los ntawm kev txav hluav taws xob. Txhua yam yog tsim los ntawm atoms, thiab txhua lub atom muaj lub nucleus ua los ntawm neutrons thiab protons nrog electrons uas orbit ncig lub nucleus. Txij li thaum lub orbiting electrons ≠ yog cov nqi me me, ib qho chaw sib nqus me me yog tsim nyob ib ncig ntawm txhua lub atom.
Yuav ua li cas hu ua magnetic field?
"Ib qho chaw sib nqus yog thaj chaw nyob ib ncig ntawm cov hlau nplaum, cov khoom sib nqus, lossis cov hluav taws xob uas muaj zog sib nqus " … rub lwm yam khoom sib nqus mus rau nws lossis thawb lwm yam khoom sib nqus tawm ntawm nws yog hu ua magnetic field.
