Hydrogen Atom (this is not chemistry!)

  1. Feb 19, 2008 #1
    1. The problem statement, all variables and given/known data
    A rather simplistic model of the hydrogen atom has a single electron revolving around a nuclear proton with an orbital radius of 5.40E-9 m at a speed of 5.00E+6 m/s. Determine the magnetic field at the proton due to the electron.

    2. Relevant equations

    B=u0*I/2piR

    I=Q/t

    V/R=2pif

    f=1/T


    3. The attempt at a solution

    I tried to do V/R to get the angular frequency, converted to frequency then period. Take the period and divide it by the charge of an electrons. After putting the current in the formula, I got 0.000873 T, but it's wrong... any suggestions?

    Your formula for B is for a long straight wire.
    Use the formula for B at the center of a current loop.
