| Nov 22 at 8:38 | comment | added | Ben | Thank you. I also have imagined that if I draw a sphere around a point in space (away from the point charge), the density of field lines is greater on one side of the circle, but over a smaller area of the circle. Summing up over the circle would result in the next flux being 0, or in other words the same number of field lines entering as exiting. | |
