Webthe curl of a two-dimensional vector field always points in the \(z\)-direction. We can think of it as a scalar, then, measuring how much the vector field rotates around a point. Suppose we have a two-dimensional vector field representing the flow of water on the surface of a lake. If we place paddle wheels at various points on the lake, WebMay 28, 2016 · The curl of a vector field measures infinitesimal rotation. Rotations happen in a plane! The plane has a normal vector, and that's where we get the resulting vector field. So we have the following operation: vector field → planes of rotation → normal vector field This two-step procedure relies critically on having three dimensions.
