Purpose
The demonstration set is intended for the experimental demonstration of the magnetic field created by electric current and the force interaction between conductors when electric current flows through them. The set provides the study of the basic concepts and patterns studied on the topics "Magnetic field of current" and the Ampere force, as well as the solution of research problems related to magnetic interaction and the structure of the magnetic field created by coils of various geometries.

Areas of knowledge and application
The demonstration set provides for studying the dependence of magnetic field induction on the current strength and the density of solenoid turns, studying the distribution of the magnetic field of a flat coil and Helmholtz rings, demonstrating the interaction of coils with current of the same and opposite directions.

What will the child learn?
The demonstration kit allows for demonstration experiments to study the dependence of the magnetic field on the current strength and to record the dependence of the magnetic field on the coordinate on a computer.
In addition, the kit provides for the computational modeling of magnetic field configurations inside a real finite-length solenoid and around a flat coil.

Updates
The demonstration kit allows you to teach the main stages of conducting an experimental study, and also allows you to conduct joint research with students.
To study the magnitude and direction of the magnetic field, a magnetic field sensor is used, the action of the sensitive element of which is based on the Hall effect.

Methodological support
The methodological manual in Russian contains instructions for performing 6 experiments on the assembled installations. The description of the experiments is accompanied by a photo of the installation and screenshots of the software, showing what results the teacher will receive during the demonstration.

Software for conducting demonstration experiments
The software for conducting experiments contains 4 scenarios for studying the dependence of the magnetic field on the current strength and recording on the computer the dependence of the magnetic field on the coordinate.
Each scenario includes optimal settings for the sensors used to conduct the experiment and for subsequent processing of the collected data.
Scenarios allow you to complete all stages of scientific research: demonstrate qualitative patterns of the observed process (more - less, increases - decreases - does not depend), conduct quantitative studies with the measurement of quantities, the formation of an observation table, the construction of a graph and comparison of the obtained experimental data with graphs of various functions, and process data using the linearization method.

Software for conducting computational modeling
The calculation model for the magnetic field of a coil provides the calculation and presentation on a computer of the magnetic field pattern that arises around a coil with current.
