what meatle stops a magnetic feald?
There is no metal that stops a magnetic field. There are metals that do not magnetize (i.e. you can't make a useful magnet out of them), but they don't stop or block an existing field. These types of metals are called non-ferrous, meaning they don't contain iron or iron oxides. A flux shield is a material used to distribute the effect of magnetic field energy across a large surface, thereby protecting the materials underneath from seeing the worst of the field's effects. It doesn't block it entirely, though. Examples of non-ferrous metals are: high-grade stainless steel (above 400 series), aluminum, titanium, sodium, magnesium, gold, and silver. There's others, but these are certainly among the most commonly used.
No specific metal stops magnetic fields but all superconductors do, metal or ceramic. In fact the most common test for superconductivity is to see if the material being tested floats above a magnet. This phenomenon is known as the Meissner effect.
first of all, I'm answering your question if you're asking, what metal stops a magnetic field? ok, so I think if it is not magnetic, and does not attract to the opposite pole, then it will stop it. but it also has to be one that if you place something that is magnetic behind the metal, it should not be attracted through the metal. if that makes any sense. try aluminum maybe. I know you shouldn't try iron. That is very magnetic. good luck!
