The magnetic field on a specific distance from a very long wire can be written as:
[tex]B=\frac{\mu_0i}{2\pi d}[/tex]Where d is the distance between the point and the wire, and i is the current. If we replace the values the exercise gives us, we're left with:
[tex]16.708*10^{-6}=\frac{4\pi *10^{-7}*50.795}{2\pi *d}[/tex]Isolating our d, we get:
[tex]d=\frac{4\pi *10^{-7}*50.795}{2\pi *16.708*10^{-6}}=0.608m=60.8cm[/tex]Thus, d=0.608m
