Electromagnetic Field Theory Gradient of scalar field is expressed as Circulation of a vector field per unit area as the area tends to zero. Outward flux of a vector field per unit volume as the volume about the point tends to zero. Maximum rate of increase of scalar function at a point. Gradient of divergence of a vector field minus the curl of the vector field. Circulation of a vector field per unit area as the area tends to zero.
