WebApr 10, 2024 · If there are no currents, i.e. in vacuum, then yes, the magnetic field will have zero curl. Most of the usual examples of magnetic fields fall into this category, and it is plenty possible for a magnetic field to have zero divergence and zero curl (want a simple example? try a constant field). WebJan 16, 2024 · Unless you put other constraints on your Helmholtz decomposition, it is not unique in general. Take any vector field which is both divergence and curl free. You can add and subtract this vector field in any way you like in the the decomposition and still come up with a Helmholtz decomposition.

"Webwhere r ′ is the variable you're integrating over. To see why this works, you need to take the curl of the above equation; however, you'll need some delta function identities, especially. ∇2(1 / r − r ′ ) = − 4πδ(r − r ′). If you're at ease with those, you should be able to finish the proof on your own. " - Curl free field

WebNov 19, 2024 · Recall that a source-free field is a vector field that has a stream function; equivalently, a source-free field is a field with a flux that is zero along any closed curve. The next two theorems say that, under certain conditions, source-free vector fields are precisely the vector fields with zero divergence.

WebIn classification of vector fields, one of the 4 different type vector fields is " solenoidal and irrotational vector field " (both divergence-free and curl-free). If solenoidal and rotational vector fields are same thing, then it means the vector field is "rotational and irrotational vector field" at the same time.

WebThink of a curl-ful field as a whirlpool--you could imagine going around and around and building up speed in it. But a curl-free field might be more like a river. You can flow down the river, but if you go back and forth down the river you spend as much time going up as you do going down, so you can't get anything out of it.

WebAn example of a solenoidal vector field, 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 ... WebIf curl of a vector field F is zero, then there exist some potential such that $$F = \nabla \phi.$$ I am not sure how to prove this result. I tried using Helmholtz decomposition: $$F = \nabla \phi + \nabla \times u,$$ so I need to show that $\nabla \times u=0$ somehow. multivariable-calculus Share Cite Follow edited Aug 4, 2016 at 16:14 Chill2Macht
