What does James Clerk Maxwell mean when he says:
"There are certain surfaces across which there is no flux. If two of these surfaces intersect, their line of intersection is a line of flux. In those cases in which the flux is in the same direction as the force, lines of this kind are often called Lines of Force. It would be more correct, however, to speak of them in electrostatics and magnetics as Lines of Induction, and in electrokinematics as Lines of Flow."
If you define a surface with the edge to the point charge it has no flux. Then what? Define a surface so the edges make an X to the charge? How is intersection of surfaces with no flux supposed to be an area?
