Produção de um aparato experimental para medição de campo magnético usando Arduino

Abstract

In this paper we focused on analyse and bring to our students a lesson where they could participate better, considering that the most aim nowadays is not a student centered work, but the achievement of numbers and goals. Our students are really tired of traditional lessons, they have a great learning potential, and we have to promote their interest in that. This led to the idea of making an apparatus using Arduino, where a learning situation was elaborated on the subject of electromagnetism and the use of an interactive and easily manipulated experiment. The study consisted on the development of a magnetic field measuring product using the Hall Effect sensor and the Arduino platform, which will interface the sensor and the computer. An apparatus was designed to assist electromagnetism classes to arouse student interest and clarify topics related to the subject. With the application of the project through the classes, it may be concluded that it is possible to study the concepts of electromagnetism, by addressing the magnetic field very clearly of the content by the student. Using the product also allows the clearly viewing of field and distance lines. Activities proposed allows the student to deduce the relationship between electric current and magnetic field, since the Arduino reads Gauss, permeating a Physics teaching that promotes students a meaningful learning.
