Experimental Scene 1 Introduction Recently, I have been deeply researching the “Do It” experiments in the new textbook section on “Electromagnetic Induction” to explore the relationship between the drop height of a magnet and the maximum value of the induced current in a coil. When using the maximum reading of a DC meter as the … Read more
Recently, the microcontroller obtained a coil and conducted a coil induction experiment using ESP32 and Phyphox. Due to the small inductance of the coil, the induction phenomenon was not very obvious, but the technical solution has been validated. If a coil with more turns and an iron core can be obtained, the experimental effect should … Read more
Experiment Scenario 1 Introduction Recently, I have been deeply studying the “Do It Yourself” experiments in the new textbook on “Electromagnetic Induction” to explore the relationship between the drop height of a magnet and the maximum induced current in a coil. The first time I used the maximum reading of a DC ammeter to represent … Read more
