Two Long, Straight, Parallel Wires Separated by a Distance D

question 2

Multiple Choice

Two long, straight, parallel wires separated by a distance d carry currents in opposite directions as shown in the figure. The bottom wire carries a current of 6.0 A. Point C is at the midpoint between the wires and point O is a distance 0.50d below the 6-A wire as suggested in the figure. The total magnetic field at point O is zero tesla.
-Determine the magnitude of the magnetic field at point C if d = 0.10 m.

• C)9.6 × 10^-5 T
• D)1.1 × 10^-4 T
• E)1.4 × 10^-4 T
