As shown in the figure below, two long parallel wires (1 and 2) carry currents of I, = 2.72 A and I, = 4.80 A in the direction indicated. (a) Determine the magnitude and direction of the magnetic field at a point midway between the wires (d = 10.0 cm). magnitude HT direction counterclockwise from the +x-axis (b) Determine the magnitude and direction of the magnetic field at point P, located d = 10.0 cm above wire 1. magnitude HT direction counterclockwise from the +x-axis
