1. The problem statement, all variables and given/known data In the Bohr-Rutherford model of hydrogen,the electron moves in a circular orbit about the proton. 2. Relevant equations I = e/t = e*v/2*pi*r I = current , e = charge , v = velocity , r = radius 3. The attempt at a solution 1)Calculated the electric current associated with that orbital motion for the ground state. 2)Determine the magnetic field at the protondut to this current.
