1. Current (6 points) Two long, parallel wires, Ax = 0.07 m apart, extend in the y direction, as shown in the figure below. Wire 1 carries a current I I = 3.7 A in the -y direction. (a) (3 points) In order for the wires to repel each other with a force per unit length of 3.1 x [0'5 Nlm, what must be the current in wire 2? Be sure to include the direction of the current in your answer. Final Exam, page 2 of 5 (b) (3 points) Now, suppose wire 2 has a current I2 = 2.3 A in the y direction. What is the magnetic eld hatf way from wire 1 to wire 2'? Be sure to specify both the magnitude and the direction of the magnetic eld. (c) (Extra Credit - 3 points) Suppose the current in wire 2 is still I2 = 2.3 A in the y direction, at what location between the wires does the magnetic eld have a magnitude of 1.1 x 10-5 T
