Force per unit length between two parallel current-carrying wires gives the common current.

For two long parallel wires carrying equal currents $I$ , separated by $d$ , the force per unit length is

$\frac{F}{L} = \frac{\mu_0 I^2}{2\pi d}$

Solving for $I^2$ with $F/L = 4.76\times10^{-2}$ N/m, $d=1.35\times10^{-2}$ m, $\mu_0=4\pi\times10^{-7}$ T·m/A: …
