Thanks all! This helped a lot.

I have been looking for this answer but have not found anything so far. I want to remake a wallet I purchased from Fossil. It has a magnetic closure for cash. Though the area sewn in is a rectangle on both the inside and outside it seems there are three small circular magnets embedded in some kind of magnetic shielded material. I have not cut my wallet open just yet to satiate my curiosity. The magnetic shielding is neat as I can get the pull of the magnet from the cash holding side but there is no magnetic field displaying on the outside. Which explains why this thing never attached to my keys or anything in my pocket. Anyone know what this is, where to buy it, or how to make it? Kindly, mere Image of my wallet:
