"WebDec 13, 2014 · For a wire carrying a steady current, all the time derivatives are zero, and ρ is zero. Therefore the electric field is zero. This leaves Ampere's Law, and the solution of that satisfies ∇ ⋅ B → = 0. That uses all of the equations. But I wonder, like @JavierBadia, whether you intend a solution that ramps the current up from zero. Share Cite " - Steady electric and magnetic fields
