Computer simulation of spectrometer magnets for some experimental installations

The significance of numerical simulation in the research of magnetic systems is determined by not only known advantages of the computing experiment, but also by the fact that the measurement of a magnetic field is a labour-consuming and expensive problem. Mathematical simulation allows one to investigate those parts of the magnet's design where the measurements of the magnetic field are extremely complicated or even impossible. This work is aimed to generalize experience of the mathematical simulation of magnetic systems of various-type physical and electromechanical installations and to work out some recommendations of the optimal use of some software products for the numerical modeling of magnetostatic problems. This work also presents some results of a numerical analysis of the magnetic systems of the JINR physical installation MARUSYA with the purpose of studying an opportunity of designing magnetic systems with predetermined characteristics of the magnetic field
