This article considers one of the parts of the development of a device for determining the magnetic characteristics of ferromagnetic materials with a shape memory effect. A functional diagram of the device has been developed. The operation of the device was simulated and the behavior of the shape memory alloy was studied. The error in determining the magnetic characteristics of the FMSF using the magnetizing setup of the developed device did not exceed 0.25%.

This article discusses the development of a magnetometer calibration device, which is controlled by a microcontroller, Arduino [1, 2], which can receive, process and transmit the necessary commands to the peripheral part of the installation using the written program code. The need for buffer circuits and elements allows you to control I / O devices. With their help, interface hardware is implemented. Structural and functional diagrams of the device were developed. And also the calculation of the parameters of the Helmholtz coils was carried out, their 3D model was built. With the help of the Gaussmeter, a full-scale experiment was carried out, which confirmed the operability of the device and its effectiveness.

When creating a model of a nonlinear electrical system based on differential equations, it is important to keep in mind that ordinary differentiation does not give an adequate mathematical idea of ​​the nonlinear physical processes taking place. Even in the simplest case of a conductor with a current, the construction of an adequate model is only possible if the tensor approach is applied. From this point of view, any electrical system is an object of tensor methodology. A typical example of a non-linear electrical system is an AC electromagnetic drive. The nonlinear nature of the processes in such devices is due to a number of reasons. The main reasons are: current displacement in the winding of the AC electromagnetic drive and saturation of the steel of the magnetic circuit in the process of magnetization. Both phenomena admit tensor description, which is confirmed by the research presented in the article.

Nowadays, it is often necessary to create effective tools for collecting, analyzing and processing information related to taking into account the activities of universities. There is also a need to develop information systems that provide automation of educational process management functions, which would reduce the cost of organizing educational process management in an educational institution. One of the primary tasks of the university is the implementation of research work by students, graduate students and research workers on the basis of research organizational structures. In this regard, an additional burden is placed on the employees of a research organization, which implies the performance of routine operations, as a result of which mistakes can be made. You can avoid possible mistakes, as well as increase the efficiency of employees by creating an information system, which is described in this article.
