A new feedback scheme for the suppression of tearing modes which are considered to be a principal cause of major disruptions in tokamak devices is proposed. Attention is focused on the suppression of the 2/1 mode as this mode strongly destabilizes the other tearing modes. Fourier components of the perturbed radial field are fed back to the toroidal field. Numerical experiments show that the feedback system is worth being discussed as a means of stabilization.
