Abstract
In this experiment, a proof of Faraday’s EM induction Law is presented using two coils, one to generate a variable magnetic flow and a second one to show an the induced electric current. Faraday’s Law says that a variable magnetic field around a cable induces a current on it, and a variable electric field produces a magnetic field. In this experiment I used an Arduino programmable board to act as a variable frequency oscillator. A voltmeter was used to measure the induced voltage on the second coil and the relationship between voltage and frequency was obtained and shown to be the curve of a high-pass filter.
