Aluminium foil will not help. Magnetic shielding must be ferro-magnetic (if I recall my electromagnetics course :-P) Easy way is to separate it by some inches or, if you must have it near electric power cords, you can shield it with mu metal. You can get some mu metal from the inside of an old television set if you have a pair of tin snips and a few minutes. It was the metal they used to build the "cage" that surrounded the yokes and the neck of the picture tube to prevent interference (either way.)
