Abstract: The electric field produced by charges at rest having been discussed in the last chapter, we now consider what happens when charges are in motion relative to each other. First it must be emphasized that Coulomb’s Law and all the electric field concepts, such as potential, derived from it are still valid; moving charges of like sign continue to experience repulsive electric forces. This was tacitly assumed in the problems of the last chapter (numbers 25 to 28) dealing with the motion of electron beams, and all experiments bear out this assumption. In addition, however, charges in relative motion interact through a second type of force called magnetic. The best way to describe this interaction is by considering that a moving charge, i.e., a current, creates a magnetic field. This magnetic field can be calculated using Biot’s Law, which we shall set up shortly, and the force experienced by a second moving charge can be expressed in terms of the magnetic field of the first.
