Hi! This might be a dum idea but here goes. Say you have 3 items. One weak magnet and two ferromagnetic materials of different susceptability. The magnet is strong enough to saturate the first material bot not the second. But since the saturated field in the first material is larger than that from the magnet, can this possibly be used to saturate the second material? If this concept works one could propagate a magnetic field through materials of different susceptabilities to get a much stronger field at the other end. Which sounds a bit crazy. Can someone explain this?
