Just as Chap. 4 was initiated with the representation of an irrotational vector field E, this chapter began by focusing on the solenoidal character of the magnetic flux density.Thus, o H was portrayed as the curl of another vector, the vector potential A. The determination of the magnetic field intensity, given the current density everywhere, was pursued first using the vector ...Conservative and Solenoidal fields# In vector calculus, a conservative field is a field that is the gradient of some scalar field. Conservative fields have the property that their line integral over any path depends only on the end-points, and is independent of the path travelled. A conservative vector field is also said to be 'irrotational ... Divergence is a vector operator that measures the magnitude of a vector field’s source or sink at a given point, in terms of a signed scalar. The divergence operator always returns a scalar after operating on a vector.
