Main Question or Discussion Point

Is there a substance that can be placed between two magnets that will stop one from affecting the other? If a sheet of paper is placed between the magnets it has no affect. This is obvious but what i want is a substance that can be placed between two magnets that are placed very close together and one magnet will have no affect on the other.

You want a magnetic shielding. You may want to look into something called "mu-metal".

Note that the effectiveness of shielding depends on the magnitude of the field. Nothing can shield a magnetic field of arbitrary strength.
