Abstract To explore the variation law of energy conversion eflicieney of electromagnetie induction devicesunder input energy sigmals, this researeh projeet desigmed and implemented a set of devices for measuring theinfluenee of loard on electromagnetic induetion emergy conversion effieieney,based on Fiaraday's Law ofEleetromagnetie Indluetion amnd using the strueture of induced eletromotive force power generation devices,Before the formal experiment, a pre-experinent was also desigmed to improve the efficieney of the energyconversion device. In the formal experiment, we ohtained a key conclusion: under energy signal input,theenergy conversion efficieney of the device first inecreases and then decreases with the increase of loadresistance, and put forvward a reasonable explanation for this phenomenon, Finally, the uncertainty of theexperimental results and error analysais were diseussed in detail. This research oot only provides new ideas andmethods for in-depth understanding of the law of energy conversion efficieney,but also has certain applicationpotential in green energy-related fields such as kinetic energy recovery and new-type power generationequipment.
