The electron in a hydrogen atom can be thought of as orbiting around the nucleus (a single proton) in a circular orbit of radius 5.28×10−11m  with a velocity of constant magnitude 2.190×106m/s . At t=  0s  a hydrogen atom is placed in a vacuum chamber that is filled with a uniform magnetic field of magnitude 3.3×1011T  pointing in the positive z -direction. The hydrogen atom is oriented such that its electron is orbiting counter-clockwise in the xy -plane at t=  0s . At t=  12s ,...
