Abstract

The invention relates to a demonstrating teaching aid of electromagnetic radiation detection, and the teaching aid can be used for demonstrating, on site, electromagnetic-field influence on the surrounding when household electrical appliances and lamps are powered on and used. The demonstrating teaching aid comprises a cuboid demonstrating casing and an electromagnetic radiation demonstration assembly, wherein the casing serves as a bearing main body of the demonstrating teaching aid, and the electromagnetic radiation demonstration assembly is arranged on the demonstrating casing, and comprises a lamp electromagnetic radiation demonstration unit and a household electrical appliance electromagnetic radiation demonstration unit. Compared with the prior art, the demonstrating teaching aid has the advantages including visual demonstration, high participation, high integrity, convenient movement and convenient maintenance.

Description

technical field [0001] The invention relates to a demonstration teaching aid, in particular to a demonstration teaching aid for electromagnetic radiation detection. Background technique [0002] Citizens are increasingly concerned about the impact of electromagnetic radiation from household appliances. At present, in the process of publicizing relevant knowledge, on-site physical testing is mainly used, combined with on-site explanation and material distribution. It is difficult to be understood and lacks comparison objects. The combination of written materials and the testing process is poor, and it is not easy to be accepted by the public. The on-site testing demonstration lacks interest and participation, resulting in poor publicity and education effects. Contents of the invention [0003] The object of the present invention is to provide a demonstration teaching aid for electromagnetic radiation detection which is intuitive to demonstrate, highly participatory, well in...
