In the Bohr model of the hydrogen atom, the electron moves in a circular orbit of radius \(5.3 \times 10^{-11} \mathrm{~m}\) with speed \(2.2 \times 10^{6} \mathrm{~m} / \mathrm{s}\). According to this model, what is the magnetic field at the center of a hydrogen atom due to the motion of the electron?
