Lagrangian analysis of the Feynman paradox




Feynman’s paradox; Lagrangian formalism; angular momentum; electromagnetic field


It is shown that the direct use of the Lagrange equations allows us to analyze the entire process involved in the Feynman paradox, without having to speak of the angular momentum of the electromagnetic field.
