Hluav taws xob yog teeny me me hlau nplaum. Lawv muaj ib sab qaum teb thiab sab qab teb ncej , ib yam nkaus, thiab tig ncig lub axis. Qhov no spinning ua rau ib qho me me tab sis tseem ceeb heev magnetic teb. Txhua electron muaj ib qho ntawm ob txoj kev taw qhia rau nws axis.
Ib yam li ntawd, puas electrons puas muaj magnetic teb?
Txawm tias ib tug atom electrons tsis txhob txav mus deb heev, lawv lub zog txaus los tsim ib qho me me magnetic teb . Txij thaum ua khub electrons tig nyob rau hauv oppositedirections, lawv magnetic teb thim ib leeg tawm.
Ib yam li ntawd, vim li cas cov electrons muaj qhov sib txawv? Qhov no yog raws li Pauli Exclusion Txoj Cai uas hais tias, hauv ib qho atom lossis molecule, tsis muaj ob electrons ua tau muaj tib yam plaub tus lej hluav taws xob quantum. Thaum twg electrons uas muaj opposite spin muab tso ua ke, tsis muaj net magnetic teb vim qhov zoo thiab tsis zoo tig rho tawm ib leeg tawm.
Ib yam li ntawd, nws nug tias, vim li cas peb thiaj muaj cov ncej qaum teb thiab sab qab teb?
Qhov txawv ncej ntawm ob lub hlau nplaum attract. Yog li ntawd, thaum lub liab kawg ntawm ib tug hlau nplaum los yog compass yog taw tes sab qaum teb , nws yog vim hais tias nws yog attracted nyob rau hauv qhov kev taw qhia ntawm lub sab qab teb kawg ntawm lwm cov hlau nplaum (feem ntau xim xiav) - qhov no yog cov hlau nplaum xav hauv lub ntiaj teb.
Puas yog electrons attracted rau North lossis South?
North thiab Sab qab teb [edit] Cov sab qaum teb ncej ntawm ib tug hlau nplaum attracts lub sab qab teb ncej ntawm lwm thaum zoo li ncej repel. Sib nqus fieldforces electrons tig ib ncig ntawm magnetic fieldlines.

Muaj pes tsawg protons neutrons thiab electrons puas muaj arsenic?
Daim duab ntawm lub nuclear muaj pes tsawg leeg thiab hluav taws xob configuration ntawm ib tug atom ntawm arsenic-75 (atomic tooj: 33), feem ntau isotope ntawm lub caij no. Lub nucleus muaj 33 protons (liab) thiab 42 neutrons (xiav). 33 electrons (ntsuab) khi rau lub nucleus, txuas ntxiv tuav cov khoom siv hluav taws xob (ntiv nplhaib)
Peb puas tuaj yeem cais tus ncej sib nqus los ntawm cov hlau nplaum?
Hloov chaw, ob lub sib nqus ncej tshwm sim ib txhij los ntawm kev sib sau ua ke ntawm txhua qhov tam sim no thiab lub sijhawm nyob rau hauv cov hlau nplaum. Vim li no, ob tug ncej ntawm ib tug sib nqus dipole yuav tsum yeej ib txwm muaj sib npaug zos thiab opposite lub zog, thiab ob tug ncej tsis tuaj yeem sib cais los ntawm ib leeg
Yuav ua li cas muaj pes tsawg electrons puas ib tug uncharged atom ntawm tin muaj?
Cov tin atom no muaj 50 protons, 69 neutrons thiab 48 electrons
Thaum lub hnub ci cua muaj zog yog hloov chaw ncej los ntawm peb cov hlau nplaum peb tau txais?
Qhov twg ntawm lub hnub hluav taws xob yog lub luag haujlwm rau cua sov lub ntiaj teb saum npoo? cov nqaij ntawm ib tug cherry piv rau lub qhov ntawm Cherry. Thaum lub hnub ci cua muaj zog tau txav mus los ntawm peb qhov chaw sib nqus, peb tau txais: cov lus qhia aurral khaus
Puas muaj ib lub hlau nplaum nrog ib tus ncej?
Nyob rau hauv particle physics, ib tug magnetic monopole yog ahypothetical elementary particle uas yog ib qho hlau nplaum cais nrog ib tug hlau nplaum (ib tug ncej qaum teb tsis muaj ib tug southpole los yog vice versa). Magnetic monopole yuav muaj anet 'magnetic charge'
