In the model of the hydrogen atom proposed by Niels Bohr in 1913, an electron circles a proton at a distance of 5.29x10^-11m, with a velocity of 2.19x10^6m / s. (a) What value of current produces the electron spinning around the proton? (b) What is the direction of the magnetic field produced by this current at the point where the proton is? (c) What is the magnitude of this magnetic field?
