Poloidal-toroidal decomposition. In vector calculus, a topic in pure and applied mathematics, a poloidal-toroidal decomposition is a restricted form of the Helmholtz decomposition. It is often used in the spherical coordinates analysis of solenoidal vector fields, for example, magnetic fields and incompressible fluids. [1]A solenoidal vector field satisfies del ·B=0 (1) for every vector B, where del ·B is the divergence. If this condition is satisfied, there exists a vector A, known as the vector …In vector mathematics, a solenoidal vector field (also called an incompressible vector field, a divergence-free vector field, or a transverse vector field) is a vector field v whose divergence is zero at all points in the field. A common way to express this property is to say that fields have neither sources nor sinks.The vector field B is solenoidal.

A vector field F is solenoidal if and only if div F = 0 everywhere in R.1,675. Solenoidal means divergence-free. Irrotational means the same as Conservative, which means the vector field is the gradient of a scalar field. The term 'Rotational Vector Field is hardly ever used. But if one wished to use it, it would simply mean a vector field that is non-conservative, ie not the gradient of any scalar field.

Solenoidal rotational or non-conservative vector field Lamellar, irrotational, or conservative vector field The field that is the gradient of some function is called a lamellar, irrotational, or conservative vector field in vector calculus.

Otherwise, if an incompressible flow also has a curl of zero, so that it is also irrotational, then the flow velocity field is actually Laplacian. Difference from material1. No, B B is never not purely solenoidal. That is, B B is always solenoidal. The essential feature of a solenoidal field is that it can be written as the curl of another vector field, B = ∇ ×A.

Cheap answer: sure just take a constant vector field so that all derivatives are zero. A more interesting answer: a vector field in the plane which is both solenoidal and irrotational is basically the same thing as a holomorphic function in the complex plane. See here for more information on that.
