Abstract: Morality and principle，insight and idea，ability and competence，knowledge and experience constitute four requisite qualities for a scientific talent. Of them，insight and idea mean capability to look far ahead and to make a foresight. In this article four elements are described to be inspired for insight and idea in the teaching practice of Electrodynamics. The first is to be good at giving an idea daringly and proving it carefully; the second is to be good at testing and verifying an idea experimentally; the third is to be good at discovering something new from a contradictory ; the forth is to be good at using mathematics for physical reasoning . The inspiration of these four elements is based on the historical facts in science. It depends on the great scientists as examples，it is blended with Maxwell equations’ understanding and applications，and it is aimed at the scientific view guidance to the students. The teaching practice of it，which has been carried out at national base for training talents for research and teaching in fundamental science (physics)at Central China Normal University，has demonstrated that it helps students promote their interest and perseverance for the Electrodynamics learning and enhance their confidence and potential for their future comprehensive development. 

Key words: electrodynamics, Maxwell’s equations, four elements for insight and idea, scientific view guidance
