Net force between three long wires (undefined length) must equal zero. Wire 1: Current going Up $$I_1$$ Wire 2: Current going Down $$I_2$$ Distance between wire 1 and wire 2 = $$d_{12}$$ How would you go about finding the location of Wire 3 relative to Wire 1 and the current $$I_3$$ of Wire 3 such that $$F_{net}=0$$ for each wire? There's equations for two wires, force per unit length $$\frac{F}{L}=\frac{\mu_0 I_1 I_2}{2\pi d}$$ But I can't seem to figure out how to use it. Or if there's something else.
