Many major breakthroughs in the history of science began with curiosity and precise verification of simple phenomena. The beginnings of electromagnetism are no exception. Today, without complex equipment, we can reenact the key steps of this leap in understanding and delve into its parameters and phenomena through carefully designed interactive experiments. The core value of this interactive inquiry lies in transforming learners from passive recipients of knowledge into active manipulators of phenomena and direct verifiers of laws. By adjusting variables (such as current magnitude and direction), observing responses (such as compass deflection and iron filings patterns), and connecting them to theoretical explanations on a touchscreen, a complete "hypothesis-experiment-conclusion" scientific inquiry cycle can be completed in minutes. Upon arriving at our large-scale "Electromagnetism" experimental setup (2800*2600*2000mm), you take over a classic electromagnetism laboratory. Your tool
