Its dynamics around this state is governed by a magnetic field regeneration mechanism similar to some extent to the dynamo naturally occurring in other physical systems. This mechanism is driven by the non-linear interaction of global, low-m resistive magnetohydrodynamic (MHD) modes resonant inside the toroidal field reversal surface. Since the outcome of this non-linear process are coherent velocity and magnetic field fluctuations, which combine to produce the dynamo electric field, energy transport in the RFP core is driven by magnetic fluctuations. %8 2000-04-01
