The curl of a vector field is one topic many students can calculate without understanding its significance. In this paper, we explain the origin of the curl after presenting the standard mathematical formulas. We investigate when and why a vector field yields an in-spot spin, also known as ...
The curl of a vector field is a measure of how fast each direction swirls around a point. The curl formula is derived by crossing the gradient with a vector and finding the determinant of this matrix. What is the curl of a vector field?

of a vector field A, the vector characteristic of a “rotating component” of field A. The curl is represented by the symbol rot A. It can be interpreted in the following manner: Let A be the velocity field of a fluid flow. At a given point of the flow we place a small wheel with...
Location of what? To calculate a curl you need a vector field, which means you need a formula that specifies the vector at each point in the space. Although your definition above says it is for a vector, not a vector field, we can interpret it as saying that the field is uniform ...
The curl of a vector field is defined as the cross product between the nabla or del operator and the vector field itself. On the other hand, the divergence of a vector field is the dot product of the del operator and the vector field. Answer and Expla...
The force vector (2) is defined by the field we are in. No derivatives or other changes are necessary -- every point in the field has some force acting on it. So, our formula for circulation is: Remember, velocity is simply the derivative of position (r), so (dr) is a vector givi...
