A Resonant Magnetic Perturbation (RMP) is an externally-induced small perturbation of the [[MHD equilibrium|equilibrium]] magnetic field,
that is resonant with it, i.e. it has the same helicity as the equilibrium magnetic field, on a given magnetic [[flux surface]],
such that it is resonant with the field at a given magnetic [[flux surface]],
usually designed to be located in the plasma edge region.
usually located in the plasma edge region.
Resonance means that the perturbation has the same [[Rotational transform|helicity]] as the equilibrium magnetic field at the target flux surface.
The perturbation typically leads to the ergodization of the magentic field around the resonant flux surface.
 
The goal is to stabilize a specific instability, mainly [[Edge Localized Modes]].
