Application of numerical analysis visualization multimedia technology in the teaching of electrical engineering

An important content in the teaching of electrical engineering courses is how to explicitly illustrate the spatial structure and operating principle of some complicated power facilities. In this paper the multimedia technology and the visualization technology on the basis of numerical analysis is carefully combined with the traditional teaching mode. The combination is sufficiently embodied in the electric machinery course. The cognition of the principle and some concepts involved in the electromotive force calculation is exemplified to illustrate the blending of teaching methods. The spatial structure of the generator can be shown in the three-dimensional multi-angle simulation model. The space and time distribution of the electromagnetic quantities is presented with the combination between the animated visualization and finite element analysis on magnetic field. Therein the man-machine interactive technology is applied to better the understanding of the cognitive difficulties. The comprehensive application of teaching methodology blended with such newly devised technology aids, the study efficiency of learners has been greatly improved.
