A segment of wire centered at the origin (x = y = z = 0) is 2.00 mm in length and carries a current of 6.00 A in the +y-direction. You measure the magnetic field due to this segment at the point x = 3.00 m, y = 4.00 m, z = 0. Find (a) the unit vector from the wire segment to this point and (b) the magnetic field at this point.
