The mathematical modeling of magnetic systems with rectangular structure for different experiments

Design, construction and operation of the magnetic systems of some electrophysical setups require a preliminary mathematical modeling as well as a constant maintenance of mathematical modeling when debugging and operating the setups. While calculating the fields of the mentioned magnetic systems (on the base of solving a number of the direct problems of magnetostatics), we are concerned with the inverse problem of magnetostatics, namely, an optimal construction of the current elements and ferromagnetic yoke was found resulting in the expected distribution of the magnetic field. This work discusses the results on the numerical modeling of the distributing magnetic field for some modifications of the spectrometric magnet SP-94, SP-40 and the magnet of solenoid type, weach used in some experimental setups.
