8-shaped coil because of its simple structure, commonly used in transcranial magnetic stimulation. Therefore, according to the induced electric field theory of the magnetic stimulation coil, the depth-induced electric field distribution is calculated for eight-dimensionally shaped coils with different radii. The study shows that the coil radius is an important parameter that affects the distribution and focusing of the induced electric field. The variation can be transcranial magnetic stimulation Coil design provides a theoretical basis.
