As the important part of the theoretical physics, the electrodynamics is a theoretical basic course of the physics and relative subjects. To adapt the demands for cultivating the target of highly-quality talents in the 21st century, the aesthetic principle can be used in the teaching to stimulate students' learning desire and cultivate students' scientific thinking ability. Combining with research experiences, the aesthetic characteristics of the electrodynamics and the application of science aesthetics in the teaching of electrodynamics are analyzed in this article.
