The classical problem of the charge and pole motion

In a previous paper the authors put forth a theoretical approach to magnetic monopoles without a string which is formulated in a Clifford bundle. To complete their theory, the authors show that the Maxwell equation---with magnetic monopoles---do imply the correct couplings of the electric current and magnetic current with the electromagnetic field (and, therefore, imply the Lorentz forces and the correct motion equations). In other words, within their Clifford approach to classical electromagnetism, the motion equations and the couplings are derivble from the field equations, without any further recourse to a variational principle and without any ad hoc postulate
