Is Divergence a Scalar?

The divergence of a vector field simply measures how much the flow is expanding at a given point. ... Hence (in contrast to the curl of a vector field), the divergence is a scalar.

Is curl a scalar?

as the curl of a plane vector field. ... The first says that the curl of a gradient field is 0. If f : R3 → R is a scalar field, then its gradient, ∇f, is a vector field, in fact, what we called a gradient field, so it has a curl. The first theorem says this curl is 0.

Is curl a vector or scalar?

In vector calculus, the curl is a vector operator that describes the infinitesimal circulation of a vector field in three-dimensional Euclidean space.
