Two infinitely long parallel wires separated by a distance d carry opposite currents of magnitude I.
a) What is the magnitude of the magnetic field at a distance r > d from the midpoint of the two wires at a location that is equidistant from the two wires?
b) If r >> d, how does the expression simplify?
