Visualization and interactive experiment of some electromagnetic problems considering cognitive features of Chinese students

This paper presents visualization and interactive experiment methods for some electromagnetic problems in electrical engineering education considering cognitive features of Chinese students. Visualization technology and interactive experiments are comprehensively used to represent the space structure of electromagnetic equipment, procedure of model creation and reasoning process, variation of currents and magnetic fields with time and their space distribution, the decomposition and resultant of the air gap magnetic field and, especially, the principles and features of rotating magnetic motive force (MMF) in AC electric machines. It has been shown that using visualization and interactive experiment technology, the students can more easily understand the complex and abstract concepts, so the teaching effect can be greatly enhanced.
