Boundary conditions on magnetostatic

  1. May 18, 2008 #1
    Hi

    I'm trying to solve a magnetostatic problem and I'm not sure which boundary conditions must be applied to the magnetic vector potential (A) on magnetostatic problems?

    Thanks in advance.

    Your boundary conditions will depend on your particular problem. Across a surface current (K) the boundary conditions are that the vector potential (A) above the current sheet is equal to vector potential below sheet. However, the derivative of A has a discontinuity:

    [tex]\partial A_{above}/ \partial n - \partial A_{below}/\partial n = -\mu_0 K [/tex]

    where n is a direction perpendicular to the plane. This article might prove to be useful to you:
