Answer:

25000 A

Step-by-step explanation:

The magnetic field can be calculated using the following equation:


B=(\mu_0I)/(2\pi d)

Where μ₀ is equal to 4π x 10^-7, I is the current, and d is the distance. So, replacing the values, we get:


0.05=(4\pi*10^(-7)\cdot I)/(2\pi\cdot0.1)

So, solving for I, we get:


\begin{gathered} 0.05=(4\pi\cdot10^(-7)I)/(0.2\pi) \\ 0.05=2*10^(-6)I \\ (0.05)/(2*10^(-6))=(2*10^(-6)I)/(2*10^(-6)) \\ 25000=I \end{gathered}

Therefore, the current is 25000 A.
