The unification of general relativity and quantum physics has become one of the most important questions of our time. The results of the analysis of cosmic ray flux variations are presented and their connection with the conditions in the interplanetary medium and the Earth's magnetosphere caused by processes on the Sun is described. According to [5,7], the dynamics of the solar wind affects the nature of the ionosphere and the current density in the global electric circuit.

Figures 1 and 2 show the results of a comparative analysis of temporal changes of the recorded modules 1 and 2 in the CARPET detector. The obtained results confirmed and showed that variations in CR intensity (Forbush decrease) are due to previous changes in the elements of the geomagnetic field caused by disturbances on the Sun. The analysis of the obtained experimental data from the installed and debugged CARPET detector of the scientific complex of L.N.

The study of the magnetic field of plasma flow provides relative information about the above mutually close factors causing plasma flow instability. In this paper, a high-frequency magnetic miniature probe has been made for measurement and further investigation of the pulsed self-generated magnetic field of plasma flow, especially at the exit of the accelerator in an experimental setup of PPA (located in KazNU, IETP). The coil inductance is about 0.113 μH and the temporal resolution of the magnetic probe is 2.3 ns.

The plasma flow is then strongly compressed radially at the accelerator exit by its self-generated magnetic field. A uniform alternating magnetic field is created in the center of the solenoid, where the measurement is made. The voltage oscillograms across the sensor and the magnetic probe obtained experimentally are shown in Fig.

As a result, the measured value of the magnetic field in the center of the multilayer solenoid with a Hall sensor at I ~ 5A was about 0.1 T. 3, typical oscillograms of the PPA current waveform (solid curve ) obtained using the Rogowski coil, the curve of the self-generated magnetic field dB/dt (dashed line) or magnetic field magnitude curves (dotted curve), obtained using a magnetic probe with and without an integrator (integration time constant τ= 5.4μs). Using the oscillograms of the output signals of the magnetic probe, the values ​​of the self-generated magnetic field of the plasma current at the exit from the coaxial electrode system (at a distance of L = 6 cm) were measured.

Moreover, in this work the processes of plasma current breakdown into discrete discharges were observed. The current density depends nonlinearly on the gas pressure corresponding to Paschen's law as mentioned above; therefore the dependence of the plasma flow rate on the gas. Initially, depending on the gas pressures and charging voltages of storage capacitors, the values ​​of the self-generated magnetic field of the plasma flow were measured.

It was found that the values ​​of the self-generated magnetic field of the plasma flow gradually decrease with an increase in gas pressure and increase with an increase in the charging voltage of the capacitors.

The technological advances of the past 15 years have made a major contribution to modern society and changed education and training. One of the newest and yet most exciting technological developments in education is the use of virtual reality (VR) and augmented reality (AR) to enhance learning opportunities. Moreover, the task at this level of education is not only to visually represent the process or phenomenon being studied, but also to present the material in an interesting, exciting way in order to captivate schoolchildren, who, unlike students, not always motivated due to their age and lack of understanding of the importance of learning.

Augmented reality is one of the newest and most promising technologies of the 21st century, which can also be used to develop virtual laboratories. Augmented reality allows you to insert virtual objects into the three-dimensional field of human perception in real time, while the augmented objects are perceived as elements of real life. Interactivity, accessibility, realism and innovation are some of the reasons for the increasing popularity and demand for augmented reality technology.

Cross-platform allows you to work on different platforms, which means a wider audience coverage and ease of use of the program. Practical tasks are carried out in the form of separate applications that provide access to three-dimensional visualization of the studied processes with the help of augmented and virtual reality technologies and problem solving. The second module is the module for the operation of the Leap Motion controller, which enables manual control of the virtual laboratory work and its elements within the virtual space.

It demonstrates the logic that ensures operation and interaction during application execution. Within each of these modules, several possible actions are available, which can also be seen in the diagram. As a result, the application provides the user with all the necessary information within the framework of the presented material, is completely safe and demonstrates complex physical phenomena and concepts.

This article gives an example of developing a software application for a virtual electronic laboratory with elements of augmented and virtual reality technologies, which includes a set of practical and theoretical tasks in physics in the form of laboratory works, as well as animations, and testing. All components of the virtual electronic laboratory are created in the form of separate modules with three-dimensional visualization of the processes and phenomena studied. The work was carried out with the financial support of the Committee of Science of the Min.
