Question

Two long, parallel wires carry currents of I1 = 2.72 A and I2 = 4.60 A in the direction indicated in the figure below. (Choose the line running from wire 1 to wire 2 as the positive x-direction and the line running upward as the positive y-direction.)
(a) Find the magnitude and direction of the magnetic field at a point midway between the wires (d = 20.0 cm).
