LEGEA LU FARRADAY
Ori de cate ori variaza in timp fluxu magnetic printr-o
dupraf oarecare apare o tens elecrtomotoare indusa. Lm = - d0 taiat m / dt
Legea sub forma locala – rotE (fortza) = -(drvpart)B(fortza) / (drvpart)t
Ori de cate ori intr-un pct al campului magn variaza in tp vect inductie apare
in juru ac camp electric rotational.OBS(rotE(fortza)=0 doar pt camp
electrostatic)
