Here the paper provides a historical and philosophical analysis of the development of electromagnetic theory in physics teaching for the benefit of scientific literacy. The analysis is described by the paradigms offered by Kuhn. A number of scientists' work in electromagnetic theory which is embedded in the tension between engaging in revolutionary science and normal science provides an insight into how scientific work is thought to proceed. The work of revolutionary scientists: Faraday and Maxwell, who were pivotal in developing the understanding of electromagnetic radiation. A group of scientists now known as the Maxwellians were integral to refining and clarifying Maxwell's theory. By realizing these things, the students will become inspired and reinforced in resolve to understand the richness of scientific discovery.
