Cumulation of laser induced magnetic field by a Z pinch device

Summary form only given. A central filament is assumed to be axially positioned inside a cylindrical shell collapsing by the Z-pinch effect. The cumulation (i.e. concentration) process is induced by generating a high magnetic field between the cylindrical shell and the filament. The initial magnetic field (of the order of few Mega gauss is generated by a circular polarized laser light)(CPLL). The inverse Faraday effect induces an axial magnetic field between the shell and the filament. Assuming a dissipationless approach, it is shown that this problem is equivalent to two point particles moving in a potential.
