Transcranial magnetic stimulation has important applications in the exploration of the causes of mental disorders and the treatment of mental disorders. A rapidly cooling magnet for transcranial magnetic stimulation has been designed. The fast cooling magnet has distributed cooling channels. Each layer of the force-bearing unit of the coil is provided with a cooling channel. The multiphysics coupled model for fast cooling magnets is established. The calculation results show that the cooling efficiency of the fast cooling magnet is 11 times that of the conventional coil. The maximum stress of the magnet is 2.45 GPa. A magnet winding process was developed that added grid cooling channels for each layer of conductors.
