(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

What is the induction in the centre of a spherical coil with N turns, the current I and the radius R?

2. Relevant equations

Biot-Savart law [tex] \mathbf{B} = \int\frac{\mu_0}{4\pi} \frac{I d\mathbf{l} \times \mathbf{\hat r}}{|r|^2}[/tex]

3. The attempt at a solution

I know what the induction from one turn is but I don't have a clue how to sum these up. And as have to have this homework done by Tuesday I'll be most grateful for any help.
