The line strength is not dependent on the path in these kinds of fields.Solenoidal vector field is an alternative name for a divergence free vector field. The divergence of a vector field essentially signifies the difference in the input and output filed lines.

But what if the vector field is conservative instead? I guess in this case it is not necessarly implied the existence of a vector potential.

An example of a solenoid field is the vector field V(x, y) = (y, −x) V ( x, y) = ( y, − x). This vector field is ''swirly" in that when you plot a bunch of its vectors, it looks like a vortex. It is solenoid since. divV = ∂ ∂x(y) + ∂ ∂y(−x) = 0. div V = ∂ ∂ x ( y) + ∂ ∂ y ( − x) = 0.

The divergence and curl of a vector field are two vector operators whose basic properties can be understood geometrically by viewing a vector field as the flow of a fluid or gas. Divergence is discussed on a companion page.Here we give an overview of basic properties of curl than can be intuited from fluid flow. The curl of a vector field captures the idea of how a fluid may rotate.Conservative and Solenoidal fields# In vector calculus, a conservative field is a field that is the gradient of some scalar field.
