Consider an XY coordinate plane. Wire A is placed along the y-axis at x=0 and wire B is placed parallel to wire A at x= 0.240 m. Wire A has a current of 2.80 A in the positive y-direction and wire B has a current of 4.10 A in the positive y-direction. Find the magnitude of the magnetic field at x=0.380 m. Give your answer in micro-tesla (?T).
