The planetary model of the hydrogen atom consists of an electron in a circular orbit about a proton. The motion of the electron of charge 1.60 × 10^-19 C creates an electric current. The radius of the electron orbit is 5.30 × 10^-11 m and the electron's velocity is 2.20 × 10^6 m/s. What is the magnetic field strength at the location of the proton?
