ON THE USE OF DEMONSTRATION EXPERIMENT IN PHYSICS IN THE EDUCATIONAL PROCESS IN HIGHER SCHOOL
At the present time in connection with the development of computer technologies has significantly increased the role of the virtual demonstration experiment. This is due primarily to the fact that the organization at the present level of full-scale experiment, as well as laboratory workshop on physics, both in secondary and higher education, requires a lot of time and serious financial costs, which is often insurmountable difficulties. However, despite all the advantages of the virtual approach, we have to admit that completely replace the real phenomenon of computer technology still can not. Physics is an experimental science and it is very useful for perception and understanding of the studied material to observe how the process actually proceeds. The authors propose to prepare and perform the experience one time with high quality, record it on a digital device, and then repeatedly use it for different audiences. As an example, this article considers a demonstration experiment prepared by the authors, illustrating the oscillations of a conductor with alternating current excited by a constant magnetic field, as well as an analytical and numerical description of this experiment. At the same time, what is important in modern conditions, for the formulation of this experience was used the most simple and affordable equipment.
