Answer:
25000 A
Explanation:
The magnetic field can be calculated using the following equation:
[tex]B=\frac{\mu_0I}{2\pi d}[/tex]Where μ₀ is equal to 4π x 10^-7, I is the current, and d is the distance. So, replacing the values, we get:
[tex]0.05=\frac{4\pi\times10^{-7}\cdot I}{2\pi\cdot0.1}[/tex]So, solving for I, we get:
[tex]\begin{gathered} 0.05=\frac{4\pi\cdot10^{-7}I}{0.2\pi} \\ 0.05=2\times10^{-6}I \\ \frac{0.05}{2\times10^{-6}}=\frac{2\times10^{-6}I}{2\times10^{-6}} \\ 25000=I \end{gathered}[/tex]Therefore, the current is 25000 A.
