| Abstract: | We offer a non-covariant derivation of the equation of motion for a dual charge, taking into account the radiation reaction, by means of a simple model of charge: a dumbbell. In the derivation we handle retarded quantities avoiding some of the usual approximations, in particular we do not restrict our calculations to first order inv/c nor overlook thet dependence ofR=|x–r(t)|. The differences with the radiation reaction problem for pure electric or magnetic charges are exhibited. |
