Abstract : The magnetic field in the polar regions may be regarded as uniform and vertical to the earth's surface. Charged particles impinging into the atmosphere in these regions follow a spiral orbit along the magnetic line of force. Since the rates of energy loss of these particles are the same in all directions, the pitch angle, alpha, of these incident particles is constant till the end of the range of the particles. In other words, incident particles maintain spiral motions with constant pitch angles, while the radius of gyration decreases corresponding to the energy loss experienced by the particle with increasing atmospheric depth.
