   The strong magnetic field of «S-turns» for generation of synchrotron emission has usually composite spatial distribution, and practically it is impossible to study the motion of corpuscles in such field analytically. In the paper the simple and reliable symplectic algorithm for numerical modeling the motion of a corpuscle in a composite magnetic field is surveyed. The input values for numerical integration - a bivariate array of field values - can be taken from results of measuring or simulation of a magnet. The motion of a charged particle through the triple-pole superconducting «S-turn" with a field maximum of 7T is surveyed as an example
