      A modification of a well-known Boris scheme is proposed for Neuton-Lorents equation solution when simulating self-consistent motion of charged particles. In general case a modificated scheme has the 2^nd order accuracy and in case of nonrelativistic motion and constant fields the accuracy reaches the 4^th order. In nonlinear case the scheme is completed with iteration algorithm. The examples of numerical calculations presented here show that the modification proposed and iteration algorithm allow to obtain more precise characteristics of a moving particle.
