Multivariate calculations of the electrodynamic accelerator with a permanent magnet support
and a ferromagnetic core are presented in the paper. The calculations were made with
using the Magnetostatic module of Maxwell/ANSYS software. The purpose of these calculations
was to determine the size and location of permanent magnets in terms of maximizing
the force acting on the projectile. In the presented paper, three cases have been analyzed. In
order to perform a comparative analysis of the obtained results of calculations, dimensions
of the rails, projectile and outer dimensions of the core were kept constant.
