One associates to a Lagrangian nonholonomic mechanical system a canonical semispray on the phase space TM, which has the integral curves given by the evolution equations of . The Lagrange geometry of the system is the geometry of semispray . We study h- and v- electromagnetic tensors and then we apply the Ricci identities for the gravitational potentials.
