Energy storage and instability in magnetic flux tubes
Abstract
A method for calculating the force-free field is proposed. It is shown that the motion of the footpoint of the field line feeds the energy into the flux tube. The instability of an over-twisted tube is also studied. The calculation could explain the motion of eruptive prominences. The energy build-up and instability in the magnetic field can be important processes in solar flares.
