Explorando o eletromagnetismo: experimento guindaste eletromagnético e sua relevância na compreensão do campo magnético

Abstract

The teaching of physics faces challenges related to the traditional approach, where students often play a passive role, resulting in an abstract and uninteresting perception of the subject. The problem is exacerbated by students' difficulty in interpreting concepts mathematically and making a connection with practical applications in daily life, especially in high school, leading to low grades and demotivation. In order to contribute to the teaching of Physics, this work focuses on experimental activities as practical tools to contextualize the teaching of physics. Practical experiments have explored a more concrete and specific understanding of physical principles, involving students in the learning process and increasing interest and motivation in the subject. The work presents an experimental tool focused on electromagnetism, developed for 3rd-year high school students. The evaluation of the activity was carried out through experimental practice, identifying the relationships between concepts and the level of understanding acquired after the practice. The results indicate that the developed activity showed a significant increase in student learning with the employed methodology, highlighting that the product used served as an evaluative tool capable of identifying areas where learning can be enhanced. In this context, we can affirm that the obtained results proved to be highly satisfactory.
