Embodiment Construction

[0037] The concrete implementation of the present invention is described in detail below, it is necessary to point out here that the following implementation is only used for further description of the present invention, and can not be interpreted as limiting the protection scope of the present invention. Some non-essential improvements and adjustments still belong to the protection scope of the present invention.

[0038] The invention provides a teaching instrument, such as figure 1 As shown, the instrument includes a base plate 1, and a first magnet 2 and a second magnet 3 respectively arranged opposite to the base plate, wherein the first magnet 2 and the second magnet 3 have different polarities, and during the setting process, the two The positions of the recipients can be exchanged without restriction. Also be provided with cutting assembly 4 on the base plate, and cutting assembly 4 is arranged in the middle of the first magnet 2 and the second magnet 3, the specific ...

Abstract

The invention provides a multimedia teaching instrument. The instrument comprises a base plate, and a first magnet and a second magnet respectively correspondingly arranged on the base plate, and a display board, wherein the first magnet and the second magnet have different polarities, a cutting component is also arranged on the base plate, and the cutting component is arranged between the first magnet and the second magnet, the display board comprises 4 induction lamps, and high precision photosensitive sensors and hot sensitive layers corresponding respectively to the 4 induction lamps. The teaching instrument can achieve intuitive and fast displaying of movement results of the magnetic induction cutting, saves the experiment space and improves the efficiency.

Description

technical field [0001] The invention relates to the field of physical electronics, in particular to a teaching instrument. Background technique [0002] With the rapid development of society, the development of automated electronic equipment is also getting faster and faster, and the demand for electronic teaching facilities in schools is also increasing. Through the electronic teaching facilities, the experimental process and results can be displayed to students intuitively and quickly, so as to help students master it in a short time and improve the teaching quality. [0003] At present, most of the experiments for cutting magnetic induction lines use a single effective length conductor to cut the magnetic induction lines between the magnets, thereby generating induced electromotive force and induced current, and reading the current value through a series of ammeters, etc. to show to students. However, the current display method is not vivid, and the experimental results...
