WebOct 14, 2024 · 1 Answer. Sorted by: 1. The flux of a vector field through a surface is a signed quantity, and is multiplied by − 1 when you change the orientation (normal direction) of the surface. If S is a closed surface then one might assume it a priori outward oriented, by general agreement. But even then the statement in the title of your question is ... WebJul 12, 2005 · 1,923. Careful when you "plug and chug". Remember that if the field points out of the surface (in the same direction as the normal) then the flux is positive; in this case the field points into the surface. Your formula would work if you used the angle that the field makes with the normal vector: that angle is 145 degrees, not 35 degrees.
