  1. Fluxul magnetic B=inductia magnetica F=BIL B=F/IL Def. Inductia magnetica este marimea fizica vectoriala definita prin forta cu care campul magnetic acctioneaza asupra unui conductor cu lungimea de 1 m aflat in camp magnetic si prin care trece un curent de 1 Amper Este o marime fizica care caracterizeaza campul magnetic din punct de vedere al intensitatii interactiuni magnetice <B>=1 Tesla(T) Pentru a face o legatura intre inductia magnetica si suprafata strabatuta sa introdus o noua marime fizica scalara numita fluxul magnetic Fluxul magnetic este marimea fizica numeric egala cu produsul dintre inductia magnetica si suprafata normala strabatuta Sn se obtine prin inmultirea suprafetei S cu versrul n care este un vector cu valoarea numerica l si cu diresctia perpendiculara pe suprafata. Formula de definitie 0=BxSn este valabila in cazul in care suprafata este perpendiculara pe liniile de camp. In caz contrar se foloseste formula 0=BxScos alfa alfa este unghiul dintre liniile de camp si versor n
