Es tsis txhob, ob magnetic ncej tshwm sim ib txhij los ntawm tag nrho cov nyhuv ntawm tag nrho cov tam sim no thiab intrinsic moments thoob plaws hauv lub hlau nplaum . Vim li no, ob ncej ntawm a Sib nqus dipole yuav tsum yeej ib txwm muaj sib npaug thiab opposite zog, thiab ob ncej tsis tuaj yeem sib cais los ntawm ib leeg.
Ntxiv mus, koj puas tuaj yeem cais cov ncej ntawm cov hlau nplaum piav qhia?
Yog , piv txwv li, kev sib cais ntawm ob ncej yog ob npaug, lub Sib nqus quab yuam diminishes rau ib - plaub nws tus nqi qub. Kev tawg a hlau nplaum hauv ob ua tsis yog cais nws sab qaum teb ncej los ntawm nws sab qab teb ncej . Txhua ib nrab pom muaj nws tus kheej sab qaum teb thiab sab qab teb ncej . Saib thiab Sib nqus dipole.
Koj puas tuaj yeem pom cov kab hluav taws xob sib nqus sab qaum teb lossis sab qab teb? North thiab sab qab teb magnetic ncej ib txwm tuaj ib leeg, peb pom qhov no hauv peb cov txiaj ntsig hauv chav kuaj. North thiab sab qab teb magnetic ncej tsuas tuaj ua khub thiab ua tau yeej tsis pom cais los ntawm ib leeg, + thiab - hluav taws xob nqi kuj tsuas yog tuaj ua khub thiab ua tau yeej tsis yog cais los ntawm ib leeg.
Kuj paub, puas muaj ib lub hlau nplaum uas tsuas muaj ib tug ncej?
Physics Discover A Magnet Tsuas Muaj Ib Tug . Magnets , raws li neeg feem coob paub, yog ib txwm dipoles: txhua hlau nplaum muaj ob sab qaum teb thiab sab qab teb ncej . PhysicistPaul Dirac tau kwv yees tias cov monopoles no yuav muaj nyob ntawm tus kawg ntawm Sib nqus hlua. Tab sis cov monopoles yeej tsis tau pom nyob rau hauv cov khoom tiag.
Vim li cas thiaj tsis tuaj yeem cais cov ncej ntawm cov hlau nplaum?
A hlau nplaum muaj sab qaum teb thiab sab qab teb ncej , zoo ib yam li cov nqi, tab sis koj ua tsis tau cais cov ncej . Yog vim li cas rau qhov no yog hais tias cov atoms los yog molecules uas tsim ib hlau nplaum txhua tus ua raws li qhov me me hlau nplaum , thiab yog aligned tomake ib tug muaj zog. Yog li nws yog cais tsis tau sab qaum teb thiab sab qab teb ncej hauv zoo li ib hlau nplaum.

Cov hlau nplaum ruaj khov puas poob hlau nplaum?
Yog lawm, nws muaj peev xwm ua tau rau cov hlau nplaum ruaj khov kom poob nws cov hlau nplaum. Muaj peb txoj hauv kev rau qhov no tshwm sim: 2) Ntawm qhov demagnetizing magnetic teb: cov hlau nplaum tas mus li nthuav tawm cov yam ntxwv hu ua coercivity, uas yog lub peev xwm ntawm cov khoom siv los tiv thaiv demagnetized los ntawm kev siv magnetic teb
Cov yas puas tuaj yeem nyiam cov hlau nplaum?
Yog li, lub magnetic teb tuaj yeem raug ntxias hauv ib qho ntawm cov hlau. Cov ntaub ntawv uas tsis nyiam cov hlau nplaum zoo li huab cua, ntoo, yas, tooj dag, thiab lwm yam, muaj ib qho permeability ntawm, qhov tseem ceeb, 1. Tsis muaj hlau nplaum induced nyob rau hauv lawv los ntawm anexternal magnetic teb, thiab yog li ntawd, lawv yog notattracted los ntawm ib tug hlau nplaum
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
Koj puas tuaj yeem tso cov hlau nplaum rau ntawm lub vaj huam sib luag hluav taws xob?
Feem ntau tsis yog, nws yuav zoo. Txawm li cas los xij, kuv yuav tsum tsis txhob muab cov hlau nplaum muaj zog nyob ze ntawm cov ntsuas hluav taws xob. Qhov tseeb ntawm qee cov qauv tuaj yeem cuam tshuam los ntawm qhov chaw sib nqus, thiab lwm tus muaj cov sensors uas yuav qhia tau tias 'tampering tshwm sim' rau lub tuam txhab hluav taws xob yog tias lawv pom qhov chaw muaj zog
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'
