Two long straight parallel wires separated by 8.0 cm carry currents of equal magnitude but heading in opposite directions. The wires are shown perpendicular to the plane of this page. Point P is 2.0 cm from wire 1, and the magnetic field at point P is 1.0 × 10ˆ’2 T directed in the ˆ’ y -direction. Calculate the current in wire 1 and its direction.
