# Motion of a charged particle in an axisymmetric longitudinal magnetic field that is inversely proportional to the radius

## Description

Abstract An exact solution to the equations of motion of a charged particle in an axisymmetric magnetic field inversely proportional to the distance from the axis of symmetry is described and a FORTRAN code computing this solution is provided. This solution involves only elementary mathematical functions, however, it requires finding a root of a transcendental equation numerically. Although not particularly complicated in principle, this process is tedious in implementation as it requires considering ...
