[Q]One question about Magnetic boundary conditions.

  1. Oct 26, 2008 #1

    You know that [tex] B_{1n} = B_{2n} [/tex] as one of the boundary condition when

    magnetic field is go across from material 1 to material 2, n means direction perpendicular to

    the boundary surface.

    I wander this theorem is right in non-uniform field which is function of space variable r.

    I read prove of this theorem that using limit so i thought this theorem is right only for close

    observation point to boundary.

    Please assist me.

    Thank you

    B1n and B2n are the fields just at the interface, but not away from it.
    That is what is meant by "boundary condition".
