Abstract:: In order to further improve the stimulation focus of the circular coil, a circular coil with deformation along different positions was designed. The spatial magnetic field distribution of the deformed circular coil was analyzed by numerical simulation at the folding position and folding angle. Compared with the conventional circular coil, the magnetic field focus of the deformed circular coil folded unilaterally at 0.5, 1 and 1.5 cm from the center of the circle was significantly improved, and the optimal folding angles were 60°~90°, 60°~105° and 75°~105°, respectively. The spatial magnetic field focus was improved by folding the deformed circular coil at 2 cm from the center of the garden on one side and at 2 cm from the center of the garden on both sides.
