Lub tswvyim ntawm hluav taws xob tam sim no

Hauv electromagnetism, tus nqi hluav taws xob uas dhau los ntawm ib qho kev hla ntawm tus neeg xyuas pib hauv ib lub sij hawm hu ua tam sim no siv, lossis tsuas yog hluav taws xob tam sim no. Lub cim rau tam sim no yog kuv, thiab chav tsev yog ampere (A), lossis tsuas yog "A" (André-Marie Ampère, 1775-1836, Fabkis tus kws kho mob thiab kws tshuaj, uas ua tau zoo heev hauv kev kawm txog cov teebmeem electromagnetic thiab kuj tau pab txhawb. rau lej thiab physics Lub thoob ntiaj teb chav tsev ntawm hluav taws xob tam sim no, ampere, muaj npe tom qab nws lub npe).
[1] Cov kev taw qhia tsis tu ncua ntawm cov nqi pub dawb hauv tus neeg xyuas pib nyob rau hauv qhov kev txiav txim ntawm lub zog hluav taws xob tsim hluav taws xob tam sim no.
[2] Hauv hluav taws xob, nws tau teev tseg tias cov kev taw qhia ntawm cov kev taw qhia ntws ntawm cov nqi zoo yog cov kev taw qhia ntawm qhov tam sim no. Tsis tas li ntawd, nyob rau hauv engineering, cov kev taw qhia ntws ntawm cov nqi zoo kuj yog siv los ua cov kev taw qhia ntawm qhov tam sim no. Qhov loj ntawm qhov tam sim no qhia los ntawm tus nqi Q uas ntws los ntawm ntu ntu ntawm tus neeg xyuas pib hauv ib lub sijhawm, uas yog hu ua qhov kev siv tam sim no.
[3] Muaj ntau hom kev thauj khoom hauv qhov xwm txheej uas nqa hluav taws xob. Piv txwv li: movable electrons nyob rau hauv conductors, ions nyob rau hauv electrolytes, electrons thiab ions nyob rau hauv plasma, thiab quarks nyob rau hauv hadrons. Qhov kev txav ntawm cov cab kuj tsim ib qho hluav taws xob tam sim no.
