  1. Mar 19, 2013 #1
    Okay I was trolling youtube (I know its a horrible habit I have that keeps me from sleeping at night) and I came across this BBC video. Its only 47 seconds but it BRIEFLY describes a material that can Focus and concentrate electromagnetic fields and I cant find anythng else on the web, any imput guys and gals on this substance? Im not even sure where to post this to be honest.

    Youtube "Concentrating and Directing Magnetic Fields" I didnt want to post the link.

    Anything with a high magnetic permeability works, like Mu-metal.
