Abstract

The invention discloses a comprehensive experiment exploration platform for an Ampere force, and belongs to a teaching or display tool, especially an experiment device for demonstrating the Ampere force in the electromagnetics. The platform is characterized in that the platform comprises a support, an electromagnetic moving device for demonstrating the Ampere force, and a permanent magnet device for providing a magnetic field. The electromagnetic moving device consists of a small rail car placed on double metal guide rails, and a square coil disposed at the tail part of the small rail car. The permanent magnet device is a U-shaped magnet assembly which is placed at the left end of a panel. The opening of the U-shaped magnet assembly is horizontally placed in a groove on the length center line of the panel. A magnetic pole is located at the top, and the outer magnetic pole is located at the bottom, wherein the magnetic pole located at the top can pass through the square coil. The platform provided by the utility model can verify the left-hand rule, and in particular, verifies the relation of the Ampere force, the magnetic induction intensity, a current and a wire length in a qualitative manner through a method of controlling variables. The platform is a novel teaching tool which is visual and simple in structure.

Description

technical field [0001] The invention belongs to educational or demonstration appliances; in particular, it is an experimental device for exploring and demonstrating ampere force in electromagnetism. Background technique [0002] There are not many innovative experiments on Ampere force, especially the very successful group experiments are rare. Students generally stay at the level of spatial imagination, and seldom experience and experience personally through experiments. The traditional demonstration equipment for ampere force in the laboratory, that is, a square coil with electricity is hung on an iron stand, the magnet is close, and the coil swing is observed. The experimental equipment is too simple and inconvenient to operate, and it is difficult to fix the spatial position, which causes great difficulties in the analysis of the spatial orientation of the ampere force, and the control variable method cannot be fully reflected. SUMMARY OF THE INVENTION [0003] In or...
