Interaction of an electric charge in the radial field of a heavy dyon

Considering one scalar potential and one vector potential for the interaction of an electric charge in the radial field of a dyon we have undertaken the study of equation of motion through Lagrangian and Hamiltonian formulations. The relation of magnetic field with the vector potential has been given a new interpretation which leads to an additional angular momentum in a direction transverse to radial direction which could be understood as spinning top like angular momentum. In presence of this additional angular momentum, the commutation relations between the components of total angular momentum and other related operators of the system take spherically symmetric forms. The Eigen value problem of total angular momentum and Hamiltonian operator has also been analysed. (author)
