Ib lub sib nqus monopole yuav muaj qhov "magnetic charge". … Magnetism nyob rau hauv bar hlau nplaum thiab electromagnets tsis yog tshwm sim los ntawm magnetic monopoles, thiab qhov tseeb, tsis muaj kev paub txog kev sim lossis kev soj ntsuam pov thawj tias muaj cov hlau nplaum sib nqus.
Vim li cas cov hlau nplaum monopole tseem tsis tuaj yeem tshwm sim?
Ib lub sib nqus monopole tsis muaj nyob. Ib yam li ob lub ntsej muag ntawm lub voj tam sim no tsis tuaj yeem sib cais ntawm lub cev, hlau nplaum North ncej thiab South ncej tsis tuaj yeem sib cais txawm tias tawg lub hlau nplaum rau nws qhov loj me. Lub teb sib nqus yog tsim los ntawm hluav taws xob thiab tsis yog los ntawm monopole.
Puas yog ib tug ncej hlau nplaum ua tau?
Rau peb txoj kev paub, nws tsis tuaj yeem tsim cov hlau nplaum ruaj khov nrog ib tus ncej xwb. Txhua lub hlau nplaum muaj tsawg kawg yog 2 tus ncej, sab qaum teb thiab sab qab teb ncej (saib FAQ txog sab qaum teb ncej). … Lawv tsis tuaj yeem muab khaws cia rau hauv ib pawg sib nqus uas ua rau lub monopole.
Leej twg tsim cov hlau nplaum monopole?
Monopoles tau xub xeeb hauv lawv daim ntawv niaj hnub ntau dua 80 xyoo dhau los los ntawm Paul Dirac, yog ib tus tsim ntawm quantum mechanics. Qhov kev tshawb pom no muaj qee qhov cuam tshuam rau physics. Magnets - Lawv ua haujlwm li cas?
Puas muaj cov nqi sib nqus?
Qhov no yog lub hauv paus ntsiab lus ntawm electromagnetic induction, nrhiav tau los ntawm Michael Faraday ntau tshaj 150 xyoo dhau los. Yog li koj tuaj yeem muaj cov nqi hluav taws xob, hluav taws xob thiab hluav taws xob, tab sis tsis muaj cov nqi sib nqus lossis sib nqus tam sim no, tsuas yog magnetic teb.

Pob hlau nplaum puas lo rau cov hlau nplaum?
Magnets lo rau cov hlau uas muaj zog sib nqus lawv tus kheej, xws li hlau thiab npib tsib xee. Cov hlau tsis muaj zog hlau nplaum muaj xws li txhuas, tooj dag, tooj liab thiab txhuas. Yuav ua li cas cov hlau nplaum lo rau cov yeeb nkab hlau?
Yuav ua li cas thiaj ua tau cov hlau nplaum monopole?
Spins zoo li ua raws li cov khoom siv sib nqus sab nraud, uas yog tus yuam sij rau kev tsim cov khoom sib nqus sib nqus monopole. "Ib lub monopole yog tsim nyob rau hauv a Bose-Einstein condensate los ntawm kev siv ib qho chaw sib nqus sab nraud los coj cov spin ntawm atoms tsim cov condensate.
Vim li cas repulsion yog qhov kev sim tiag tiag rau kev txheeb xyuas cov hlau nplaum?
Repulsion yog qhov kev ntsuam xyuas tseeb rau cov hlau nplaum vim nws tshwm sim tsuas yog thaum ob lub zoo li cov hlau nplaum muaj nyob thaum qhov kev nyiam tshwm sim tuaj yeem tshwm sim ntawm ob tsis zoo li tus ncej ntawm cov hlau nplaum thiab ntawm cov hlau nplaum thiab cov hlau nplaum.
Puas yog daim nplaum nplaum nplaum nplaum?
Scotch® Siv dav Daim Ntawv Ncauj Ncaujtuav rau qhov chaw ntev txog 3 hnub thiab tom qab ntawd tshem tawm tau yooj yim yam tsis muaj cov nplaum nplaum tom qab. Zoo heev rau daim ntawv lo, ntim khoom, thiab daim ntaub npog ntsej muag rau ntawm qhov chaw uas tsis muaj kev puas tsuaj.
Puas yog av nplaum nplaum nplaum thaum ci?
Baking polymer av nplaum ntawm qhov kub li niaj zaus tuaj yeem tsim cov ntxhiab tsw uas tuaj yeem ua rau cov neeg rhiab heev. Ntau yam tib yam li qee cov tshuaj tsw qab ua rau koj mob caj pas lossis mob taub hau yog tias lawv muaj zog heev. … Npog av nplaum thaum lub sij hawm ci yuav txo qhov tsw.
