Research on Teaching Aid of Analog Circuits Based on Magnetic Element
In the traditional teaching process of analog circuit course, the connected circuit element and current trend are not intuitive and students understand difficultly. In order to solve this problem, the teaching aid of analog circuit based on magnetic elements is researched and designed, including a DC power supply, some element modules and some connecting soft lights, both ends of the connecting soft light has a connecting plug connection, element module is comprised of bottom plate, switch, socket, input slot, output slot, symbol and permanent magnet, input slot and output slot are communicated together , switch and symbol are communicated together, permanent magnet is located at the bottom of the component module. By a plurality of component modules absorbed on the surface of iron blackboard that are marked with the symbol to make up the teaching circuit, by shining of connecting soft lights to simulate the current in the circuit, the teaching content of analog circuit is vividly demonstrated and understanding of students for teaching content is improved.
