Solenoidal vector field.

It follows from the definition of the Lie derivative that the volume form is preserved under the flow of a solenoidal vector field. Thus solenoidal vector fields are precisely those that have volume-preserving flows. This fact is well-known, for instance, in fluid mechanics where the divergence of a velocity field measures the compressibility ...In fact, the electric and magnetic fields are different facets of the same electromagnetic field, and in moving from one inertial frame to another, the solenoidal vector field portion of the E-field can change in whole or in part to a B-field or vice versa. Lorentz force and Faraday's law of induction Lorentz force -image on a wall in LeidenA vector field F is said to be conservative if it has the property that the line integral of F around any closed curve C is zero: ∮ C F · d r = 0. Equivalently F is conservative if the line integral of F along a curve only depends on the endpoints of the curve, not on the path taken by the curve, ∫ C1 F · d r = ∫ C2 F · d r.Properties. The fundamental theorem of vector calculus states that any vector field can be expressed as the sum of an irrotational and a solenoidal field. The condition of zero divergence is satisfied whenever a vector field v has only a vector potential component, because the definition of the vector potential A as:. automatically results in the identity (as can be shown, for example, using ...

That would be a physical example. For a general one, you could define said vector field using the conditions by construction. $\endgroup$ -solenoidal fields... hello forum, curl and divergence are "local" concepts. If a vector field has zero divergence it means that there is no source (or sink) at that point. It could be divergenceless everywhere. If the field is solenoidal it automatically is divergenceless. I do not understand why a solenoidal field needs to have closed lines ...Unit 19: Vector fields Lecture 19.1. A vector-valued function F is called a vector field. A real valued function f is called a scalar field. Definition: A planar vector fieldis a vector-valued map F⃗ which assigns to a point (x,y) ∈R2 a vector F⃗(x,y) = [P(x,y),Q(x,y)]. A vector field in space is a map, which assigns to each point (x,y,z ...1 Answer. It's better if you define F F in terms of smooth functions in each coordinate. For instance I would write F = (Fx,Fy,Fz) =Fxi^ +Fyj^ +Fzk^ F = ( F x, F y, F z) = F x i ^ + F y j ^ + F z k ^ and compute each quantity one at a time. First you'll compute the curl:

The spaces W1,p(Ω),H1(Ω) are the standard Sobolev spaces.When ϕ∈ W1,1(Ω) then ∇ϕ:= (D 1ϕ,...,Dnϕ) is the gradient of ϕ. For our analysis we only require some mild regularity conditions on Ω and ∂Ω.

The curl of a vector field, denoted curl(F) or del xF (the notation used in this work), is defined as the vector field having magnitude equal to the maximum "circulation" at each point and to be oriented perpendicularly to this plane of circulation for each point. More precisely, the magnitude of del xF is the limiting value of circulation per unit area. Written …Here, denotes the gradient of .Since is continuously differentiable, is continuous.

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.
