Question:

What materials block a magnetic field?

I was looking around the house for something that would block the attraction of magnets. I‘ve stuck two magnets on opposing sides of just about every non conductor I could find. Some reduced the strength of the magnets trying to stick together but they still stuck. Thanks

Nothing blocks magnetic fields. You can put ferromagnetic materials (like mu metal) to divert magnetic fields around a space, but the magnetic fields are just constrained to lie mostly within the metal, the field strength is increased, and there is still some field present outside it (on both sides). Any metal can that magnets are attracted to, will provide some shielding (as I describe above). Your test using two magnets doesn't do what you thought.
