I will qualify my questions /comments with the fact that I am not a materials science , chemistry, atomic physics, or electrochemical, engineer or scientist. that being said, I am thinking from atomic and material domain perspective that a material such as copper, chromium, nickel, bismuth . . . can they be superheated (just heated) to their phase changing point while exposed in an intense magnetic field then cooled. Will they (or some other materials) be pre disposed to create or at least more easily create current or voltage when a magnetic field is moved in proximity . . . or the materials are moved in proximity to each other?
