A model to explain the observed, approximately 1/f, power spectrum of the X-ray variability in low luminosity Seyfert is developed. The proposed model involves a current carrying mass filament in the corona of an accretion disk. Using arguments similar to the ones for solar flares, the amount of magnetic energy which can be stored inside the tube is estimated. The equilibrium configuration of the tube is studied. It is concluded that magnetic flares can occur and the tube will subsequently break up. The kinetic energy of particle beams which result from this flare process is determined. Inverse Compton loss times and emitted power from the beams are calculated and they seem to fit the observations. Possible means of verification of the model are indicated.
