Is there anything that is none electrical that would block a magnetic field?
I'm doing a small experiment with my son for a science project and we are looking for magnetic resistance in typical household objects. So far we have found nothing. Glass. plastic, paper, water, nonferrous metals, wood, you name it. Of course it depends on the thickness of the material and the strength of the magnet. We are working with small neodymium magnets.
There exist several nickle-iron (plus some other impurities, like molybdene) alloys that can do that: mu-metal, permalloy, supermalloy, nilomag, sanbold. Mu-metal is often used for shielding of magnetic fields in household appliances.
