Magnetic Shielding for cables is done by wrapping the MuMetal FeNi80Mo foil and your job is pretty much done. Magnetic shielding applications of round or rectangle or square objects. A magnetic field does not travel in a straight line; it works Up and Down. It travels all around. To shield objects you need to prepare a round or cone shape and shield it!
