About magnetic shielding materials

  1. Sep 28, 2006 #1
    Hi all...

    I was trying to understand the theoretical basis of Magnetic Shielding and I stuck at the point that materials with high permeability concentrate (attract or conduct) the magnetic field, so that the magnetic field lines change its path (redirected) and pass through the material instead of the air, for instance. (as shown in the figure)


    could anyone explain why?

    or, I can put the question in another form:
    why ferromagnet materials (or materials with high permeability)concentrate magnetic field lines?
