SUMMARY Magnetic stimulation is a way of stimulating nervous and muscular tissue with an electric field induced by a stimulation coil and is widely used in evaluation of the nervous system and in the field of exercise physiology. The focality and the deep stimulation efficiency of magnetic stimulation are affected by the coil arrangement and the shape of the stimulated object, since the induced electric field distribution is varied by these factors. In this study, we used a five‐layer head model and estimated the induced electric field distribution by calculation. The results indicate that the induced electric field distribution is mostly affected by the boundaries between tissues with different conductivities.
