1. A wire carries current I from infinity down along the +y axis to the origin and then out the +r axis to infinity. Find the magnetic field B(x, y) at any point in the quadrant r > 0, y > 0. Hint: you may consider using the principle of superposition to add the field contributions from each current-carrying wire segment to find out the total field at position (x, y). Also note that there is a certain symmetry between x and y coordinates in the given current distribution, so once you've calculated the contribution from one of the segments, you may not need to do the other one from scratch
