## Abstract

One of the most important applications of the electric and magnetic fields deals with the motion of charged particles. For instance, in experimental nuclear fusion reactors the study of the plasma requires the analysis of the motion, radiation, and interaction, among others, of the particles that forms the system. In biomedicine the use of accelerators, like the cyclotron, allows the preparations of compounds to be employed in diagnostics, such as the FDG (see Problem 11.5), which is used as a tracer in the detection of some kinds of cancer and body diseases by means of the PET technique. Or in a closer case, the Earth, where its magnetic field, acting like a particle mirror, protects us against many of the cosmic rays.
