A number of different types of coils exist, each of which produce different magnetic field patterns. 1  Some examples: 2  round coil: the original type of TMS coil. 3  figure-eight coil (i.e., butterfly coil): results in a more focal pattern of activation. 4  double-cone coil: conforms to shape of head, useful for deeper stimulation.
