Constants of motion in a helical magnetic field
Abstract
The relationship between the ''screw'' symmetry of a helical magnetic field and the constants of motion of the system is obtained. In particular, the integral of motion for the symmetry is derived and the relationship between this integral and one obtained by Laird and Knox is demonstrated.
