I was thinking that maybe I could use Biot Savert's (sp.) law

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

and

[tex]d\textbf{F} = q\textbf{v} \times d\textbf{B}[/tex]

but, as I mentioned earlier, I don't have a good application for that. Worse comes the worse, I could try and write a program to do it, but

- I don't know what method of approximation to use, and
- I'm not very good at coding.
