Abstract

Knowledge of Eddy currents is being used increasingly in the development of various technologies. The researcher then created a test to survey the understanding of 124 grade 12 Bangkok Christian College students about Eddy currents and the use of the right-hand rule to determine the direction of Eddy currents on metal sheets. The results of the survey, there was the average number of students with a sound understanding (SU) was 13.44 % and found a large number of students with a specific alternative conception (SAC), average 67.81 %. Only 2-4 students were able to correctly determine the direction of the Eddy currents on metal sheets. It shows that most students do not understand Eddy currents. The results of this study can be used to develop learning management to change the level of students' alternative conceptions to the correct scientific understanding and have a good attitude towards studying physics in the future.
