This video illustrates the calculation of vector field flux. It begins by demonstrating a uniform vector field on a flat plane using vertical arrows and provides the standard dot product formula for planar flux. The concept is then extended to curved surfaces by introducing surface elements that approximate planes locally. Finally, it derives the total flux as a double integral over the surface area.
