The exact formula for the magnetic force per unit length between two parallel current-carrying conductors:

$\frac{F}{l} = \frac{?_{0} I 1 I 2}{2 ? d}$ For more information, check: Force between parallel conductors

$B = N \frac{μ_{0} l}{2 μ}$

$B α \frac{N}{μ}$

$\frac{β_{x}}{β_{y}} = \frac{N_{x}}{r_{x}} \times \frac{r_{y}}{N_{y}}$

$\frac{B_{x}}{B_{y}} = \frac{200}{20} \times \frac{20}{400} = \frac{1}{2}$

$B_{A} = \frac{μ_{0} I θ}{4 π R}$

$\Rightarrow \frac{B_{A}}{B_{B}} = \frac{I_{A} θ_{A} R_{B}}{I_{B} θ_{B} R_{A}}$

$\Rightarrow \frac{2 (\frac{3 π}{2}) (4)}{3 [\frac{5 π}{3}] [2]}$

$\Rightarrow \frac{6}{5}$ .

$m (L) = m_{1} S_{1} (Δ T)$

$\Rightarrow m (3.4 \times 10^{5}) = (200) (4200) (25)$

$\Rightarrow m = 61.7$
