TECHNIQUE FOR CONDUCTING LABORATORY WORKS FOR STUDYING THE PHENOMENA OF ELECTROMAGNETIC INDUCTION

Abstract

The article deals with the problem of professional orientation of teaching physics to students of the profile class of natural and mathematical direction. As one of the approaches to solving this problem, the authors propose the use of laboratory works of practical orientation, used in the study of physics by students of technical universities, which are processed under the program of the school course of physics. The scheme of installation and stages of performance of this work and processing of experimental data in the conditions of school is considered. The proposed installation for laboratory work allows to simulate the work of many sensors, sources of magnetic field, including Helmholtz coils. Students, using the phenomenon of electromagnetic induction, in the course of work measure the thickness of the part with the accuracy provided by micrometers, get acquainted with the principles of remote measurement of the amplitude and frequency of electric alternating currents; and measure the distribution of the magnetic field created by one or two coaxial coils. It is noted that the implementation of this work is of interest to students and increases the general interest in the subject of physics. The introduction of such works in the school physics course is highly desirable.
