Curl

In vector calculus, the curl is a vector operator that describes the infinitesimal rotation of a vector field in three-dimensional Euclidean space. At every point in the field, the curl of that point is represented by a vector. Curl is an extension of torque.

Given a vector field $𝐅$, the curl of $𝐅$ can be written as $\mathrm{curl}𝐅$ or $\mathrm{\nabla }\times 𝐅$, where $\mathrm{\nabla }$ is the gradient and $\times$ is the cross product operation.
