A general method for calculating the selfinduced magnetic force of an axisymmetric toroidal current
Abstract
A method is presented for computing the class of axisymmetric current distributions flowing in a torus whose peripheral surface is a flux surface for the magnetic field produced by the current itself. The method allows the correct calculation of the ‘selfinduced’ magnetic forces arising from the interaction between these currents and their own field. The general expression for the selfinduced force is given and an approximate formula is presented in the large aspectratio limit.
