As one of the most traditional branches of physics, complete theoretical system of electromagnetics has been constructed for a long history. This makes electromagnetics naturally contain rich curriculum ideological content, including scientific ideas, exploratory spirit  and national confidence. In this paper the educational connotation of the course is condensed and the ideological and political elements are systematically collected and organized based on the educational connotation. The ideological and political elements of the course are organically integrated into the teaching design according to the teaching content. Some ideological and political elements of electromagnetism are shown in this paper. Taking two teaching segments as examples, part of the teaching design considering integrating ideological and political education is shown.
