Patterns of Fields in Space Box versus open surface Seem to be able to tell if there are charges inside no clue Gausss law: If we know the field distribution on closed surface we can tell what is inside. Patterns of Fields in Space Need a way to quantify pattern of electric field on surface: electric flux 1. Direction flux>0 : electric field comes out flux<0 : electric field goes in +1-1 Relate flux to the angle between outward-going normal and E: flux ~ cos( ) Electric Flux: Direction of E 2.
