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 , the curl of  can be written as  or , where  is the gradient and  is the cross product operation.
