what you need is a Faraday Cage. And yes, they work. The proof is that your computer isn't preventing your cell phone to work, because it IS in a faraday cage (the metal box that holds it in place... yes, the one with the "on/off" button and all those holes to plug your usb key in... :-P )

Such a material does not exist. The only answers I can give you is a second magnet (with an opposite pole) and distance. There is no material that can prevent or absorb the magnetism. That would be neat though.

The only "insulator" for magnetic fields is a superconductor. Magnetic lines of force are expelled from superconductors due to the Meisner Effect.

Some materials like ferrite will concentrate the magnetic force lines in themselves so reducing the field outside. But there are no materials that will stop the field.

A magnetic field cannot penetrate an iron (or any metal that can be magnetic) box.
