What is the physical meaning of curl of gradient of a scalar field ...

In vector calculus, the curl is a vector operator that describes the infinitesimal circulation of a vector field in three-dimensional Euclidean space. The curl at a point in the field is represented by a vector whose length and direction denote the magnitude and axis of the maximum circulation. The curl of a field is formally defined as the circulation density at each point of the field. WebEdit: I looked on Wikipedia, and it says that the curl of the gradient of a scalar field is always 0, which means that the curl of a conservative vector field is always zero. But then can you go the other way and say that a vector field is conservative if it has a curl of 0? WebDetermine whether the following vector field is conservative on \( R^{3} \). If so, determine a potential function \[ F=\left\langle 3 x^{3}, 4 y^{4},-6 z\right) \] Select the correct choice below and fill in any answer boxes within your choice. A. The field is conservative.

Curl of a vector is zero

Can a non-zero vector field have zero divergence and zero curl?

WebWith the next two theorems, we show that if F is a conservative vector field then its curl is zero, and if the domain of F is simply connected then the converse is also true. This … WebF is a gradient field. Now up to now I thought that whenever the curl of a vector field equals 0, firstly the vector field is a gradient field and secondly the integral around every closed paths equals 0. So this would make the second and the third statement to be correct whilst the first statement obviously would be wrong.
