I have a tricky problem here. Using biot-savart's law, I need to find an expression for the magnetic field inside a loop anywhere on the plane of the loop. I am not expected to solve the integral, only set it up.

2. Biot-Savart's law is...

[tex]d\textbf{B} = \frac{\mu_0}{4\pi} \frac{Id\textbf{l} \times \textbf{\hat{r}}}{r^2}[/tex]

3. I can solve for along the axis, but I am at a loss for how to do this problem. Any tips for solving would help! Thank you, this is an amazing site.
