Ukuhamba kombane

Livela

Kwi-electromagnetism, i-flux yombane ngumlinganiselo webala lombane ngomphezulu onikiweyo, [1] nangona intsimi yombane ngokwayo ayikwazi ukuhamba.

Indawo yombane u-E inokukhupha amandla kwintlawulo yombane nakweyiphi na indawo kwindawo. Intsimi yombane yi-gradient yesakhono.

Intlawulo yombane, njenge-electron enye esithubeni, inomhlaba wombane oyijikelezileyo. Kwifom yemifanekiso, le ntsimi yombane iboniswa njengechaphaza, intlawulo, i-radiating "lines of flux". Ezi zibizwa ngokuba imigca yeGauss [2] Qaphela ukuba imigca yentsimi ingumfanekiso ocacileyo wamandla entsimi kunye nesikhokelo kwaye ayinayo intsingiselo yomzimba. Ubuninzi bale migca buhambelana namandla ombane, anokuthiwa kwakhona ukuxinana kombane: inani le "lines" kwindawo yeyunithi. Umbane oguquguqukayo ulingana nenani lilonke leentambo zombane ezihamba kumphezulu. Ukwenza lula ekubaleni, kudla ngokuba lula ukuqwalasela umphezulu we-perpendicular kwimigca yeflux. Ukuba intsimi yombane ifana, umbane ohambayo odlula kwindawo ye -vector S
