Abstract: The characteristics and coupling process of coupled pendulum are analyted. The approach to simu-late coupled pendulum with mutual inductance is proposed. With a kind of homemade simulation device based on series LC circuit, the coupling of oscillation and energy exchanging process between two pendulums are demonstra- ted. As the mathematical equations of the mechanical coupling and mutual inductance coupling are nearly same, to compare these two kinds of coupling models will help students to improve their capability of mathematical modeling and the ability of analyzing complex system.
Key words: coupled pendulum, mutual inductance coupling, mathematical modeling
