Hello,(adsbygoogle = window.adsbygoogle || []).push({});

Is there a general, analytic way to obtain a vector potential for a prescribed magnetic field? I.e. to solve

[tex]\vec \nabla \times \vec A = \vec B[/tex]

for [tex]\vec A[/tex]?

I'm looking for something like what e.g. the Green's function method is for Poisson's equation, so the answer might be a complicated integral but it is a definite, closed solution.

Best,

Nikratio
