Understanding electromagnetic induction, whose study is part of the middle school curriculum in Japan, is difficult for students. Thus, this study developed an augmented reality (AR) teaching aid for electromagnetic induction for middle school students. Magnetic lines are illustrated in three dimensions as an AR using conventional tablet PCs. Lessons were conducted with 127 middle school students, and the changes in their explanation of the principle of electromagnetic induction were investigated before and after using the teaching aid. The investigation revealed that only 3% of the students could explain scientifically the principle of electromagnetic induction before using the teaching aid; however, 63% of them were able to provide a scientific explanation after the AR teaching aid was applied.
