1. The problem statement, all variables and given/known data
Two infinitely long perfectly conducting planes at x = 0 and y = 0 form a boundary on the upper right quadrant (x > 0, y > 0). A magnetic dipole m = m_x + m_y [with their corresponding unit vectors] is located at at (x', y', z' = 0) in the upper right quadrant. Find the magnetic field everywhere in the upper right quadrant.

Now I think that I can solve the problem using method of images and the usual boundary conditions for normal B and tangential H. But what is the actual significance of conducting plates for magnetostatics?


2. Relevant equations



3. The attempt at a solution

You answered your own question in the previous sentence. :)

Well. To put it in another way. How would the boundary conditions change in case the sheets were made out of dielectrics. As far as I understand, there cannot be any difference.

Thanks a lot for answering. I had given up on it.

I will assume that you meant permeable material instead of dielectric. The dielectric boundary conditions on the magnetic field are trivial. What is the image of a magnetic dipole in a perfectly conducting surface? What is the image of a magnetic dipole in the surface of a permeable material? Do you have a textbook? The answers to these questions can be found in Jackson (with a little persistence).
