WOW this problem is making me mad. I know force between two wires is mu*I1*I2*L/2pi*d. Ive used this and tried to find the magnitude but it says its wrong. What Am i doing wrong? I made sure to subtract the two forces one going up and one going down.

There are 3 wires all parallel. Each carries 10 A. The top one is to the right. middle is to the left. and bottom is to the right. Find the force magnitude on the top wire. there Lengths are 50cm.and each are separated by 2cm.
