Ok, here's the question....
Obviously materials with low reluctance are great for magnetic shielding because they can easily redirect the flux from one pole back to the other pole without apparently affecting the object being shielded.
What I don't understand is why doesn't it affect the shielded material?
If the shielding medium has a low reluctance it's magnetic domains line up along the flux lines and in doing so would become a magnet themselves??? And then wouldn't they just as easily affect the material that it is meant to be shielding?? Is this a bad assumption???
