Chapter 1 Introduction
... Since the particle is heavy, a motion along the x axis can be described in a classical fashion. This is true, but for quite subtle reasons, and again we will come to that later. So as a net effect, the particle will fly through the inhomogeneous magnetic field, and it will “feel” an upward force if ...
