Suppose an electron orbits a proton at a distance of 'r' with speed 'v'.(adsbygoogle = window.adsbygoogle || []).push({});

How could i determine the magnitude of the magnetic field at the location of the proton?

I thought it would make sense to use The Biot-Savart Law, but i dont know where to begin:

[tex]dB = \frac{\mu_o}{4\pi} \frac{I ds x r}{r^2} [/tex]

(where [tex]ds x r[/tex] is a cross product of ds and r (unit vector) )
