Definition:Rotational Vector Field

Definition
Let $R$ be a region of space.

Let $\mathbf V$ be a vector field acting over $R$.

Then $\mathbf V$ is a rotational vector field the curl of $\mathbf V$ is not everywhere zero:


 * $\curl \mathbf V \not \equiv \bszero$

That is, $\mathbf V$ is not conservative.
