JEE Main 2024 (Online) 27th January Evening Shift Physics - Magnetic Effect of Current Question 39 English Explanation

$\begin{aligned} \frac{μ_{0} i}{2 R_{2}} (\frac{π}{2 π}) \otimes + \frac{μ_{0} i}{2 R_{1}} (\frac{π}{2 π}) \otimes \\ (\frac{μ_{0} i}{4 R_{2}} + \frac{μ_{0} i}{4 R_{1}}) \otimes \\ \frac{4 π \times 10^{- 7} \times 4}{4 \times 4 π} + \frac{4 π \times 10^{- 7} \times 4}{4 \times 2 π} \\ = 3 \times 10^{- 7} = α \times 10^{- 7} \\ α = 3 \end{aligned}$
