Use some kinda of ferrous casing around what ever you want to protect. This way the magnetic field will go around the outside of the case. This is how hard drives are protected. If you don't know what I am talking about, go look at he magnetics field of a ring magnet. Or go put a magnet up to a steel washer and sprinkle iron filings on it to visualize the magnetic field.

we are studying this in physics right now, so someone please correct me if I am wrong. This is just what I have been taught, No experience with this.
