I believe.. regardless of what the current direction or for that matter the magnitude in the middle wire is, the answer should be zero! . But not in the options!

I think the problem is wrong, it should be calculate the force on the conductor C

Please check this one http://faculty.kfupm.edu.sa/phys/kuhaili/PHYS102Exams_T111/Chapter29.pdf question number 23.. even that is wrong ?.. cause regardless of what direction or magnitude current is.. net force has to be zero!

no, if current in wire 2 is in the opposite direction to current in wire 1. the net force on 3 would be zero.

But you also need a certain magnitude to make it zero.

No the question is, what is the net force on WIRE 2, the middle wire.. As long as the current in side 2 wires are same and in same direction, the force on wire 2 will always be zero!

\[\frac{\mu L I_2}{2\pi \cdot \frac12 } = \frac{\mu L I_1}{2\pi \cdot 1} \implies I_2 = \frac{I_1}{2}\]
