Pistão magnético com um solenóide: um estudo sobre eletromagnetismo e transformações de energias

Abstract

This work consists of the construction of an experimental apparatus called a magnetic piston and the development of a didactic sequence as support material for teaching Physics in the third year of high school. The research was theoretically based on the authors Young, Hugh D. (2015), Kazuhito and Fuke (2016), Hewitt, Paul G. (2015), among others. The approach adopted is qualitative in nature, aiming to deepen and detail the understanding of the phenomena involved in the proposed experiment. The development of the work involved the assembly of the prototype and the analysis of its operation, with the objective of observing the physical phenomena involved. In this context, the transformations of electromagnetic energy into mechanical energy were demonstrated through the magnetic field generated by the solenoid. Furthermore, the relationship between direct current, magnetic force, and magnetic field in the operation of the experimental apparatus was illustrated. Based on this, a didactic sequence is proposed with the objective of structuring the concepts addressed, interconnecting theory and practice. The experiment is used as a pedagogical tool to demonstrate the physical phenomena involved, facilitating students’ visualization and understanding.
