This study aims to analyse, based on common characteristics of the Nature of Science, how first year university Physics textbooks present the introduction of the concept and theories of magnetic field. It shows that despite the increasing number of studies into the Nature of Science in Science Education, Physics textbooks fail to adopt the results of this research. It is proposed that it would be plausible for textbooks to illustrate the characteristics of the Nature of Science by focusing on problems and changes in the development of the theory of magnetic field.
