On Rotating Charged Dust in General Relativity. III

An earlier paper considered an exact cylindrically symmetric interior solution of the Einstein-Maxwell equations for rotating charged dust corresponding to a definite constant ratio of the charge and mass of the particles. In this paper a new, exact cylindrically symmetric interior solution is found which corresponds to an arbitrary constant ratio of the charge and mass. An interesting property of the new solution is that it is regular and well behaved for certain values of the parameters occurring in it.
