Utilizando o captador de guitarra como sensor: Construindo um kit para abordar a Lei de Faraday em sala de aula

Abstract

The approach to the concept of electromagnetic induction in physics education can present challenges, particularly regarding its distance from students' everyday experiences. The functioning of an electric guitar pickup can serve as an interesting example to contextualize the topic, allowing students to understand the correlation between the variation in magnetic field flux and the induced electromotive force. This study aims to present a low-cost project to explore Faraday's Law of Induction through an experimental kit composed mainly of an electric guitar pickup, an electric motor with a speed controller, a Light Dependent Resistor (LDR) sensor, and permanent magnets.
