An electromagnetic model for charged particle with spin

An electromagnetic model for charged particle with spin in the framework of Born-Infeld type nonlinear electrodynamics is considered. The field configuration having two dyon singularities with identical electric and opposite magnetic charges is introduced and it is named bidyon. The sum of two dyon solutions when the dyons may have velocities with equal modules and opposite directions on a common line is considered as the initial approximation to the bidyon solution to a nonlinear electrodynamics model. The associated field configuration has a constant full angular momentum which is independent of a distance between the dyons and their speed. The dynamical system with two dyons can have an oscillating regime. The possibility for model representation of leptons with the bidyon solution is discussed.
