Aiming at the problem that how to locate the induction devices′position automatically in the wireless power trans-mission system, the influence of the transverse displacement of the induction devices on the coupling coefficient be-tween the induction devices is analyzed, and the whole core coil simulation analysis is been done by the large-scale finite element software COMSOL, which have also been verified through experiments. The results show that the coupling coefficient between the induction devices decreases first, then increases, finally decreases with the in-crease of induction devices′transverse displacement. The theoretical result has positive effect on the efficiency measuring of the whole system, and which is helpful to the research on the automatic location of induction devices.
