DP 6.1 (50 points) The two long, parallel wires shown in the figure are separated by a distance d = 2.0 cm and carry currents in opposite directions of i, = 2.5 A and i2 = 1.0 A, respectively. N. Find the magnitude and direction of the net magnetic field at point P, a point in between the wires a distance x = 0.67 cm to the right of the P wire on the left. I -X- Wire 1 Wire 2 DP 6.2 (50 points) A solenoid is designed such that the magnetic field at the center of the solenoid has a magnitude of 8.0 x 10-3 T when carrying a current of 5.0 A. If the solenoid contains 1845 turns of wire, what length must the solenoid be
