Flux is integral along flat curve

The flux of a vector field exiting a boundary flat curve is defined as the line integral of the component of the field normal to the curve along the curve.

Conditions:

  1. The normal to the curve is outward (see right-hand rule).

  2. The vector field is continuously differentiable everywhere within the region of the surface.

  3. The curve is closed and flat.
