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.

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 .
Puas muaj cov hlau nplaum sib nqus?
Raws li txhais los ntawm nws lub npe, cov hlau nplaum monopole muaj ib tus ncej, tsis zoo li dipole, uas muaj ob lub sib nqus ncej. Tam sim no tsis muaj pov thawj rau lub neej ntawm cov hlau nplaum sib nqus, tab sis lawv yog qhov nthuav dav .
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.
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 .
