INFORMATION ASPECTS OF EDUCATIONAL RESEARCH EXPERIMENTAL PROBLEMS IN ELECTRODYNAMICS
Description
The article discusses the experimental task, the analysis of which cannot be carried out without the use of methods of calculus mathematics. It is shown that the use of modern information technology in educational research tasks to confront theory with real physical experiments lets us raise the level of quality of training future teachers of physics and computer science

COMPUTER TECHNOLOGIES IN THE ANALYSIS OF A COMPLEX PHYSICAL PROBLEM
Description
The article discusses the technology of using modern computer tools in the educational process of preparation of teachers of physics in the analysis of a complex modern problem. We consider the experimental task, the analysis of which cannot be carried out without the use of methods of calculus mathematics. A massive conductor in the form of a solid cylinder is placed in a quasi-stationary magnetic field. It is necessary to find the parameters of the magnetic field in the volume of the conductor. An algorithm for developing a program of numerical study of the radial dependence of the field in the conductor is given. The graphs of dimensionless amplitude of the field and of the phase shift relative to the external field at different are drawn where и are the radius and conductivity of the material of the cylinder, is the frequency of the external field, h is a dimensionless radial coordinate equal to . The graphs let us “see” what is going on with the field inside the conductor with the change of control parameters z and h. We demonstrate the self-organization of the test field with increasing z, which happens because of the nonlinear feedbacks. It is shown that the use of modern information technology in educational research tasks to confront theory with real physical experiments lets us raise the level of quality of training future teachers of physics and computer science. The use of this method in the educational process of pedagogical (physics) and technical institutes of higher education is recommended

Description
We consider the technology of application of numerical methods in the educational process in physics on the example of a study of the magnetic field induced by induction currents in a cylindrical conductor in a quasi-stationary magnetic field. Here is given the numerical calculation of the real and imaginary parts of the Bessel functions of complex argument. The listing of the program of drawing the graphs of the radial dependence of the amplitude and phase shift of the inductive currents field is cited. The graphs of the dependence of the parameters of the field on the radial coordinate for different values of the control parameter are drawn. The control parameter z is proportional to the frequency of the external magnetic field, the conductivity of the material and the square of the radius of the cylinder. When z is less than 1, the amplitude of the field of currents increases in proportion to z, and decreases quadratically with the increasing radial coordinate h. For a larger z the amplitude and the phase shift relative to the external field change nonlinearly with the increase of h. It is concluded that there exists a significant difference between the inductive currents field and the total field in the cylinder equal to the sum of the external field and the currents field. The nonlinear connection between these fields is explained. The use of this method in the educational process of pedagogical (physics) and technical institutes of higher education is recommended
