Unformatted text preview: vector field that is directed along the x-axis, its curl can have nonzero components along y or z directions. Example: This vector field has a curl along the negative-z axis. In other words, the z-component of the curl for this vector field measures how the above vector field changes in the y-direction. As an another example, consider the velocity field in a river, that would something like the following: This vector field will have an upward curl near the upper bank ( U ) of the river and a downward curl near the bottom bank ( B ). Imagine the shape of the vector field which is curl of the above field. y x B U...
