Abstract

The present invention relates to the technical field of popular science education, in particular to an Oster experimental demonstration device suitable for science popularization venues, comprising a table body and a table top arranged on the table body. A battery, an ammeter, an active wire and a switch, and several compass needles are arranged around the active wire. The present invention is an Oster experimental demonstration device suitable for science popularization venues. The switch is used to connect the circuit. The ammeter shows whether there is current passing through the circuit. The battery provides power. Learn the magnetic effect of current by observing the changes of the pointer of the compass around the active wire when the current passes or does not pass.

Description

technical field [0001] The invention relates to the technical field of science popularization education, in particular to an Oster experiment demonstration device suitable for popular science venues. Background technique [0002] The Oersted experiment is a key experiment for students to understand the magnetic field generated by current, and it is very important for students to understand magnetic phenomena. At present, there are many teaching aids used to demonstrate Oersted experiments to students in China. Most of these teaching aids require students to connect circuits and observe experimental phenomena by themselves. These teaching aids are very good for teaching. However, if they are used in popular science venues It has certain limitations. The popular science venues require students to participate in the interaction freely and independently, so as to learn knowledge. While considering student interaction, we should also consider the normal operation of popular scie...
