【Abstract】 A Pi-bundle formalism for the Born-Infeld electrodynamics is proposed and the equation of motion for a test particle in the Born-Infeld electromagnetic field is given. There are two forces acting on the test particle, one corresponds to the Lorentz force and the other the Poincaré stress.更多还原
