Show that the magnetic vector potential for two long, straight, parallel wires carrying the same current, I, in opposite directions is given by: A→ = μ 0I / 2π ln(r1/r2)n^
where r2 and r1 are the distances from the field point to the wires, and n^ is a unit vector parallel to the wires.

The two required components for a generator are
