I am wondering if there is a magnetic shield available that will not get atracted to either magnet, but will stop the North and South of two magnets from seeing eachother. cana Diamagnetic material do it? | ||

The only thing I can think of is a superconductor. Im pretty sure that would work, but it probably wont suit your application (cryo temperatures, etc.) | ||

There is no normal temperature materials? | ||

I'm thinking lead or alluminum. | ||

That might work... Any ideas Simon? | ||

Neither lead nor aluminum will affect magnetic fields much at all. Anyone with two magnets and a piece of aluminum foil can verify this in a minute or two. Usually, someone who is interested in "magnetic shielding" but does not want to use any of the commercially available magnetic shielding materials, is interested in generating power from the effect. They are fogetting that it takes energy to put the shield in place, and to remove it, and that the energy it takes is greater than the energy produced. You can't get something from nothing (First Law of Thermodynamics). You can even break even (Second Law of Thermodynamics). |
