What I am trying to do is magneticly shield half of a magnet, so that only one side is magnetic.
Here is an illustration of what I would like to do:
My first question, obviously, is will it work? I know things like computer speakers are magneticly shielded, but I'm not sure exactly how, or if it would work for only one side of a magnet.
My second question is, would the strength of the magnet, or it's lifespan, be comprimised?
My third, and hopefully final, question, is what material would be ideal for shielding? I've heard brass and copper will work best, as I obviously don't want the shielding material to be magnetic.
Any help with any of these questions would be great. Thanks!
