英文摘要：

This paper presents the calculating models for the magnetic field radiation of the power sup- ply cable which is laid in a common way and an optimal layout to depress the magnetic field radiation of the cable. The simulations and experiments show that the computing models are of high accuracy and so can be used to analyze the magnetic field radiation caused by the cable and to guide the optimal design of the cable. Thus, there is no need for repeated simulations and experiments, so that both the time and cost of design can be reduced.
