You want make the largest possible B field at some location (some point in space) by running a current through a piece of copper wire of length L that you already have, with a battery of voltage V that you also already have. What is the best possible shape and size for the wire to take on? What is the largest B (an equation) based on V, L, resistivity of copper (ρ), and any other parameters - geometric or otherwise - that can be created?
