Lingaliro la mphamvu yamagetsi

Mu electromagnetism, kuchuluka kwa magetsi komwe kumadutsa mu gawo lililonse la kondakitala pa unit time kumatchedwa current intensity, kapena kungoti electric current. Chizindikiro cha current ndi I, ndipo unit ndi ampere (A), kapena kungoti "A" (André-Marie Ampère, 1775-1836, wasayansi wa ku France komanso wamankhwala, yemwe adachita bwino kwambiri pakuphunzira za zotsatira za electromagnetic komanso adaperekanso thandizo ku masamu ndi physics. Unit yapadziko lonse ya electric current, ampere, imatchedwa dzina lake).
[1] Kuyenda kwanthawi zonse kwa ma free charges mu kondakitala pansi pa mphamvu yamagetsi kumapanga magetsi.
[2] Mu magetsi, zimanenedwa kuti njira yoyendetsera kayendedwe ka mphamvu zabwino ndi njira yoyendetsera kayendedwe ka mphamvu. Kuphatikiza apo, mu uinjiniya, njira yoyendetsera kayendedwe ka mphamvu zabwino imagwiritsidwanso ntchito ngati njira yoyendetsera kayendedwe ka mphamvu. Kukula kwa mphamvu zamagetsi kumafotokozedwa ndi mphamvu ya Q yomwe ikuyenda kudutsa gawo la kondakitala pa nthawi ya unit, yomwe imatchedwa mphamvu ya mphamvu zamagetsi.
[3] Pali mitundu yambiri ya zonyamulira zamagetsi zomwe zimakhala ndi mphamvu zamagetsi. Mwachitsanzo: ma elekitironi osunthika m'ma conductors, ma ayoni m'ma electrolytes, ma elekitironi ndi ma ayoni mu plasma, ndi ma quark m'ma hadrons. Kuyenda kwa zonyamulira izi kumapanga mphamvu zamagetsi.
