Explanation: If a vector field A → is solenoidal, it indicates that the divergence of the vector field is zero, i.e. ∇ ⋅ A → = 0. If a vector field A → is irrotational, it represents that the curl of the vector field is zero, i.e. ∇ × A → = 0. If a field is scalar A then ∇ 2 A → = 0 is a Laplacian function.

Certainly a solenoidal vector field is not always non-conservative; to take a simple example, any constant vector field is solenoidal. However, some solenoidal vector fields are non-conservative - in fact, lots of them. By the Fundamental Theorem of Vector Calculus, every vector field is the sum of a conservative vector field and a ...The homogeneous solution is both irrotational and solenoidal, so it is possible to use either the vector or the scalar potential to represent this part of the field everywhere.
