Summary:The invention relates to a multi-source difference method and device for evaluating an electromagnetic model of an implantable medical device. The method comprises the following steps: applying excitation to a target cable by using a plurality of excitation sources at different positions with the same excitation signal to obtain multiple measurement results. Wherein the measurement result comprises an electromagnetic field parameter in an environment where the target cable is located and a current parameter generated on the target cable. Secondly, acquiring a position relationship between the target cable and each pair of excitation sources; and finally, determining a collaborative electromagnetic model of the target cable according to multiple measurement results and the position relationship. The influence of a real measurement error on the constructed electromagnetic model is greatly reduced, so that the electromagnetic model capable of more accurately reflecting the characteristics of the target cable in
