Three parallel wires carry currents I1=4.0 AI_1 = 4.0 \text{ A}, I2=2.0 AI_2 = 2.0 \text{ A}, and I3=6.0 AI_3 = 6.0 \text{ A} all in the same direction. Wire 2 is positioned midway between wires 1 and 3, which are separated by distance d=0.20 md = 0.20 \text{ m}. What is the direction of the net magnetic force on wire 2?
