Can a vector field be the curl of another vector field?
You can determine whether a vector field can be written as the curl of another vector field (in R3) by looking at it’s divergence. Assume a vector field F can be written as the curl of another vector field, call it G. Then F=curl G.
What is the curl of a solenoidal vector?
The curl of any vector field always results in a solenoidal field! a result that is always true for any and every vector field ( )r A . S )! In other words the surface integral of any and every solenoidal vector field across a closed surface is equal to zero.
What is the condition for a vector field solenoidal?
If there is no gain or loss of fluid anywhere then div F = 0. Such a vector field is said to be solenoidal. A key point: F is a vector and the curl of F is a vector.
Why is electric field curl zero?
For an electrically charged body, the net outflow integral is never zero. So the curl must be zero since lines of force do not form closed curves but diverge or converge. Since curl E =0, E can be expressed a gradient of a scalar potential V since curl grad V always vanishes.
What is Solenoidal in vector?
In vector calculus a solenoidal vector field (also known as an incompressible vector field, a divergence-free vector field, or a transverse vector field) is a vector field v with divergence zero at all points in the field: A common way of expressing this property is to say that the field has no sources or sinks.
What does it mean when curl is zero?
If the curl is zero, then the leaf doesn’t rotate as it moves through the fluid. Note that the curl of a vector field is a vector field, in contrast to divergence.

What is a Solenoidal?
A solenoid is a device comprised of a coil of wire, the housing and a moveable plunger (armature). When an electrical current is introduced, a magnetic field forms around the coil which draws the plunger in. More simply, a solenoid converts electrical energy into mechanical work.
